PMR03
Resistors
Ultra low ohmic resistors for current detection
PMR03
Outline PMR03 in the 0603 package (1.6x0.8mm) works at the rated power of 0.25W, which is the first in the industry for its size using metal-plate as resistive element and is achieved by Rohm's unique production method. The suitable application is the battery meter in portable appliances, and also the current control circuit (which is down-sizing these days) and the over-current protection circuit.
Features 1) Metal-plate, which is an excellent material in view of electrical characteristics, is employed as resistive element by Rohm's unique production method. 2) 0.25W is achieved; the industry's first for 0603 sized metal-plate type. 3) 150ppm/C of TCR (Temperature Coefficient of Resistance) is realized at ultra-low resistance of 10m 4) Completely Pb free product
Applications Note PC, HDD, mobile phone, small battery-unit, charger, DC/DC converter, general power-supply units
