Ultra-low Ohmic Chip Resistors for Current Detection
PMR Series
Features
1)
2)
3)
4)
Ultra low-ohmic resistance range (1m ~ )
Improved current detection accuracy by trimming-less structure.
Special low resistance temperature coefficient.
The unique chip structure minimizes thermal stress during temperature cycling,
resulting in greater reliability.
5) ROHM resistors have obtained ISO9001 / ISO / TS16949 certification.
6) Corresponds to AEC-Q200. (PMR50 / 100)
