14 sv/h series guide to applications for tantalum chip capacitors the failure of the solid tantalum capacitor is mostly classified into a short-circuiting mode and a large leakage current mode. refer to the following for reliable circuit design. 1. field failure rate sv/h series tantalum chip capacitors are typically applied to decoupling, blocking, by-passing and filtering. the sv/h series has a very low failure rate in the field. for example, the maximum field failure rate of an sv/h series capacitor with a dc working voltage of 16 v is 0.0002 %/1000 hour (2 fit) at an applied voltage of 5 v, operating temperature of 25 c and series resistance of 3 w . the maximum failure rate in the field is estimated by following expression: ll = ? ? ? ? - ? ? ? ? 0 0 3 10 2 0 v v tt l : maximum field failure rate l 0 : 0.5%/1000 hour (the failure rate of the sv/h series at the full rated dc working voltage at operating temperature of 85 c and series resistance of 3 w .) v : applied voltage in actual use v 0 : rated dc working voltage t : operating temperature in actual use t 0 :85 c the nomograph is provided for quick estima- tion of maximum field failure rates. connect operating temperature t and ap- plied voltage ratio v/v 0 of interest with a straight line. the failure rate multiplier f is given at the intersection of this line with the model scale. the failure rate is obtained as l = l 0 f. examples: given v/v 0 = 0.4 and t = 45 c, read f = 4 10 C3 . hence, l = 0.002%/1000 hour (20 fit). given v/v 0 = 0.3 and t = 25 c, read f = 4 10 C4 . hence, l = 0.0002%/1000 hour (2 fit). 120 110 100 90 80 operating temperature t (?c) failure rate multiplier f applied voltage ratio v/v 0 70 60 50 40 30 20 10 ? 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 2 4 7 10 ? 2 4 7 10 ? 2 4 7 10 ? 2 4 7 10 ? 2 4 7 10 0 2 4 7 10 1 2 4 7 10 2
15 sv/h series 2. series resistance as shown in figure 1, reliability is increased by inserting a series resistance of at least 3 w /v into circuits where current flow is momentary (switching circuits, charge/discharge circuits, etc.). if the capacitor is in a low-impedance circuit, the voltage applied to the capacitor should be less than 1/2 to 1/3 of the rated dc working voltage. 10 1 magnification of failure 0.1 0.1 1 series resistance ( w /v) 10 100 figure 1. effects of series resistance 3. ripple voltage the sum of dc voltage and peak ripple voltage should not exceed the rated dc working voltage of the capacitor. figure 2. permissible ripple voltage vs. frequency figure 2 is based on an ambient temperature of 25 c. for higher temperature, permissible ripple voltage shall be derated as follows. permissible voltage @ 50 c = 0.7 permissible voltage @25 c permissible voltage @ 85 c = 0.5 permissible voltage @25 c permissible voltage @ 125 c = 0.3 permissible voltage @25 c 100 10 1 0.1 0.1 1 frequenc y (khz) ripple voltage (vrms) 10 100 case: a, b 2 @ 25 c 35 v 25 v 20 v 16 v 10 v 100 10 1 0.1 0.1 1 frequenc y (khz) ripple voltage (vrms) 10 100 case: c, d 2 @ 25 c 35 v 25 v 20 v 16 v 10 v
16 sv/h series 4. reverse voltage because the capacitors are polarized, reverse voltage should not be applied. if reverse voltage cannot be avoided because of circuit design, the voltage application should be for a very short time and should not exceed the following. 10% max. of rated dc working voltage @25 c 5% max. of rated dc working voltage @85 c 1% max. of rated dc working voltage @125 c 5. mounting (1) direct soldering keep in mind the following points when soldering the capacitor by means of jet soldering or dip soldering: (a) temporarily fixing resin because the sv/h series solid tantalum capacitors are larger in size and subject to more force than the chip multilayer ceramic capacitors or chip resistors, more resin is required to temporarily secure the solid tantalum capacitors. however, if too much resin is used, the resin adhering to the patterns on a printed circuit board may adversely affect the solderability. (b) pattern design aca b case a b c a 2.9 1.7 1.2 b2 3.0 2.8 1.6 c 4.1 2.3 2.4 d2 5.4 2.9 2.4 the above dimensions are for reference only. if the capacitor is to be mounted by this method, and if the pattern is too small, the solderability may be degraded. (c) temperature and time keep the peak temperature and time to within the following values: solder temperature ............ 260 c max. time ................................. 10 seconds max. whenever possible, perform preheating (at 150 c max.) for smooth temperature profile. to maintain the reliability, mount the capacitor at a low temperature and in a short time whenever possible. (d) component layout if many types of chip components are mounted on a printed circuit board which is to be soldered by means of jet soldering, solderability may not be uniform over the entire board depending on the layout and density of the components on the board (also take into consideration generation of flux gas).
17 sv/h series (e) flux use resin-based flux. do not use flux with strong acidity. (2) reflow soldering keep in mind the following points when soldering the capacitor in a soldering oven or with a hot plate: (a) pattern design aca b case a b c a 1.6 1.7 1.2 b2 1.6 2.8 1.6 c 2.4 2.3 2.4 d2 2.4 2.9 2.4 the above dimensions are for reference only. note that if the pattern is too big, the component may not be mounted in place. (b) temperature and time keep the peak temperature and time to within the following values: solder temperature .............. 260 c max. time: 10 seconds max. whenever possible, perform preheating (at 150 c max.) for smooth temperature profile. to maintain the reliability, mount the capacitor at a low temperature and in a short time whenever possible. the peak temperature and time shown above are applicable when the capacitor is to be soldered in a soldering over or with a hot plate. when the capacitor is soldered by means of infrared reflow soldering, the internal temperature of the capacitor may rise beyond the surface temperature. (3) using soldering iron when soldering the capacitor with a soldering iron, controlling the temperature at the tip of the soldering iron is very difficult. however, it is recommended that the following temperature and time be observed to maintain the reliability of the capacitor: iron temperature ......... 300 c max. time ........................... 3 seconds max. iron power .................. 30 w max.
18 sv/h series 6. cleaning generally, several organic solvents are used for flux cleaning of an electronic component after soldering. many cleaning methods, such as immersion cleaning, rinse cleaning, brush cleaning, shower cleaning, vapor cleaning, and ultrasonic cleaning, are available, and one of these cleaning methods may be used alone or two or more may be used in combination. the temperature of the organic solvent may vary from room temperature to several 10 c, depending on the desired effect. if cleaning is carried out with emphasis placed only on cleaning effect, however, the marking on the electronic component cleaned may be erased, the appearance of the component may be damaged, and in the worst case, the component may be functionally damaged. it is therefore recommended that the r series solid tantalum capacitor be cleaned under the following conditions: [recommended conditions of flux cleaning] (1) cleaning solvent ......... chlorosen, isopropyl alcohol (2) cleaning method ......... shower cleaning, rinse cleaning, vapor cleaning (3) cleaning time .............. 5 minutes max. *ultrasonic cleaning this cleaning method is extremely effective for eliminating dust that has been generated as a result of mechanical processes, but may pose a problem depending on the condition. as a result of an experiment conducted by nec, it was confirmed that the external terminals of the capacitor were cut when it was cleaned with some ultrasonic cleaning machines. the cause of this phenomenon is considered metal fatigue of the capacitor terminals that occurred due to ultrasonic cleaning. to prevent the terminal from being cut, decreasing the output power of the ultrasonic cleaning machine or shortening the cleaning time may be a possible solution. however, it is difficult to specify the safe cleaning conditions because there are many factors involved such as the conversion efficiency of the ultrasonic oscillator, transfer efficiency of the cleaning bath, difference in cleaning effect depending on the location in the cleaning bath, the size and quantity of the printed circuit boards to be cleaned, and the securing states of the components on the boards. it is therefore recommended that ultrasonic cleaning be avoided as much as possible. if ultrasonic cleaning is essential, make sure through experiments that no abnormality occur as a result of the cleaning. for further information, consult nec.
19 sv/h series 7. others (1) do not apply excessive vibration and shock to the capacitor. (2) the solderability of the capacitor may be degraded by humidity. store the capacitor at (C5 to +40 c) room temperature and (40 to 60% rh) humidity. (3) exercise care that no external force is applied to the tape packaged products (if the packaging material is deformed, the capacitor may not be automatically mounted by a chip mounted).
