PRECISION METAL FILM DMR
The DMR range is available in power ratings from 1/6W to 2W. The
DMR25 offers a nominal 0.6W power rating in a standard 1/4W
size. Resistors are manufactured to JIS-5202
specifications and tested following MIL-R-22684, giving
repeatable performance between batches.
All product is coloured light blue with an easily readable
5-colour code.
Operating Temperature:
-55°C to 155°C
