TOKEN LPS Low Ohm Current Sensing Resistors Low Ohm Current Sensing Resistors 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.
