Design Notes

VITROHM offers a range of low-ohm resistors for current sensing applications, resistance ranges typically from 1 milliohm to 100 milliohms.
These devices are of non-wound construction and made from flat resistive alloy wire.
The resistor's specification depends on the material and the choosen dimensions, namely specific-resistance, thermal conductivity and temperature coefficient are of importance.

BWF-Series – an alternative for resistor - fuse - combinations

This series has been specially developed, to offer an alternative for resistor-fuse-combinations.

CRF-Series - made especially for mains-applications

While series BWF is made for the widest range of applications, parameter of CRF-series are designed for circuits with clearly defined failure-mode-conditions.

SLR/SLP Resistors

Additionally to existing styles of their Low-Ohm (shunt) resistors, VITROHM now offers the resistance range of 10 mOhms to 3,3Ohms in flat (slim-line) ceramic cases.
