Token’s Low Resistance, Low Inductance,
Open-Air Resistor is Alternative Shunts (LRB)
Preview
Developed for current sensing and shunt applications, Token’s LRB series of bare element resistors have a
precision alloys (Ni-Cu) element welded construction. Built-in stand-offs and standard spacings make for easy
mounting.
The bare metal element design allows for maximum cooling via airflow, forcing less heat into the PCB. The
flameproof construction offers values down to 2mΩ with low inductance. Customer can specify resistance range
designed to satisfy challenging and specific technical requirements.
These factors make the LRB Series an outstanding choice for all types of high current power supplies and
power applications requiring a robust part that is impervious to most environmental stresses. The device is ideal
for current limited, Current balance, and sampling sense in power supplier. It takes on the capability of high
overload, and the function easily welding and non inductance as well.
The LRB Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical
requirements and special applications,
please contact us with your specific needs.
