Current sense resistor

KOA Speer Electronics introduced the new SLN3 molded current sense resistor, featuring a 3-W power rating in 4528 size. The SLN3 is a molded resin resistor that provides excellent dimensional accuracy, mountability, and shock resistance. Due to its metal plate terminal electrode, it also offers enhanced terminal strength, heat and shock resistance, and solderability. KOA Speer’s SLN3 resistor has low TCR (temperature coefficient of resistance) available down to ±75 ppm with resistance tolerance as low as 0.5% and an operating temperature range of -55 to +180°C (-67 to +356°F). It will be offered in resistance values of 5 mΩ up to 110 mΩ. The AEC-Q200 qualified resistor is a surface-mount type with flameproof UL94V0 molded case. Used primarily for current detection, SLN3 current sense resistors are suitable for transportation, industrial, telecommunications, and consumer electronics markets in applications such as personal computing devices, dc-to-dc conversion, automotive modules, motor control and power supplies. Lead time for the SLN3 is 12 weeks; samples are available upon request.
