Also Offering RoHS Compliant Equivalent Parts Low-Voltage / High Q Si Hyperabrupt Varactors Mounting Information The illustration indicates the recommended mounting pad configuration for the SC-79, SOT-323 and SOD-323 packages. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices. These varactors are available in the three case styles shown. When ordering, specify the desired case style by adding the case designation (287 for SOT-23, 1146 for SOT-323, 1141 for SOD-323) as a suffix to the model number. For example, MA4ST230-1141 specifies the MA4ST230 varactor in the SOD-323 package. The model number indicated is for a single varactor. Common cathode pairs are available in SOT-23 package, and are specified by adding "CK" to the end of the model number. For example MA4ST230CK-287 specifies the MA4ST230 varactor in common cathode pairs. For RoHS Compliant Parts, use the Following Suffices for the Given Package Style ( After the Base P/N ) : SC-79 : 12790T SOD-323 : 11410T SOT-323 : 1146FT As example, the RoHS P/N for the Base P/N MA4VR-000230 in SOD-323 is : MAVR-000230-1146FT.
