AEC-Q200 qualified: Current sensing resistor with T.C.R to 75ppm

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 mΩ and 75 mΩ in 1206 size.

The UR73V-series is available from 10 mΩ to 100mΩ and is available in 0805 and 1206 sizes.

Features:
• 10 mΩ to 100 mΩ
• 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
