Metal plate shunt resistors <ultra low ohmic>
PMR series
1/4
2022.10 - Rev.012
●Features
1) Ultra low-ohmic resistance range (1mΩ ~ )
2) Improved current detection accuracy by trimming-less structure.
3) Special low resistance temperature coefficient.
4) The unique chip structure minimizes thermal stress during
temperature cycling, resulting in greater reliability.
5)
ROHM res
istors have obtained ISO9001 / IAFT16949 certification.
6)
Co
r
responds to AEC-Q200
.

●Chip resistor dimensions and markings
■PMR 01 / 03 / 10 / 18 ■PMR 25 / 50 / 100
<Marking method>
There are four digits used for the calculation
number "L" is used for the decimal point of mΩ.
Ex.) 2mΩ = 2L00
10mΩ = 10L0
