PMR03_11 Datasheet, PDF (1/4 Pages) Rohm – Ultra low ohmic resistors for current detection

Ultra low ohmic resistors for current detection
PMR03
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) 0 to +150ppm/C of TCR (Temperature Coefficient of Resistance) is realized at ultra-low resistance of 10m
4) Completely Pb free product

Rated voltage
Rated current
Rated voltage and current are determined from the following.
E= P×R
E= P / R
E: Rated voltage (V)
I : Rated current (A)
P: Rated power (W)
R: Resistance (Ω)
