KOA’s UR73V-series thick film low ohm resistors are designed for current detection, especially in demanding environments. The special facedown construction makes lower resistance values with a low T.C.R. of ±75 ppm/K possible. The low T.C.R of new UR73V-series and its wide operating temperature range of -55 °C to +155 °C make it ideal for applications such as automotive or high reliability DC-DC converters.
The T.C.R. of ±75 ppm/K is specified for resistance values between 12 mΩ and 75 mΩ in 1206 size and between 15 mΩ and 100 mΩ in 0805 size. The UR73V-series is available from 10 mΩ to 100mΩ and is available in 0805 and 1206 sizes. The UR73V series can be a more cost-effective alternative to “metal plate” shunt resistors.
