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. 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 15 mO and 75 mO in 1206 size.
The UR73V-series is available from 10 mO to 100mO and is available in 0805 and 1206 sizes.
Features:
- 10 mO to 100 mO
- 0.5 W (0805 size), 0.75 W (1206 size)
- AEC-Q200 qualified
- ±1 % tolerance
- Lower cost alternative to metal plate parts
- Standard and face down type available
- Improved high temperature reliability
(operating temperature -55 °C to +155 °C)
Applications:
- Automotive, including "under the hood" applications such as ECUs
- Power supplies
- DC-DC converters
- Motor controls
- Industrial automation
- Meter
- LED Lighting
