Token (LPS) Family Offers A Variety of
Possibilities for Shunt-Resistors
Preview
Token’s current sense LPS family for shunt-resistors is
expected to gain wide acceptance in the worldwide market
as a result of offering a variety of possibilities.
The U-shaped semi-customized LPS family for direct board
mounting is specified for current sensing, feedback, current
detective, supper low inductance, as well as surge and pulse
applications. LPS family Available in very low ohm
(0.002Ω ~ 0.05Ω) and high power (1W ~ 5W).
The dimensions of the semi-customized final unit is designed
in accordance with the applicational requirements of resistance
value and required power rating. Token’s LPS series can be
manufactured with 2 or 4 soldertags (terminals). The LPS type B with 2 soldertags (1 pin on each side) is a
standard part of LPS series and type A with 4 terminals (2 pin on each side) is used either for Kelvin connections
or for high current applications. Depending from the alloy material’s thickness, one terminal contact on each side
can carry up to 50A (A (Current) = (W (Power)/Ω (Resistance))1/2), so a 4-terminal part can carry 100A (ask
Token factory).
Operating temperature range is -50°C to 300°C with tolerances ±2%, ±5%, and ±10%.
Token will also produce low ohm resistor LPS series outside these specifications to meet customer requirements.
