low ohmic resistors - lra series

low ohmic resistors lra series

low ohmic resistors lra series

lr series are super low resistance (2mΩ ~) and suitable for high power ac/dc detection of power supply circuit.


all low ohmic power type are non-inductive type and custom-made products. please contact token sales for more information.

construction: the resistive elements consist of a flat metal-band. spot welded cu-terminals ensure high stability of contacts. thus, this construction results in a non inductive of both high stability and overload capacity.
