Precision resistor has a low temperature coefficient and small outline

July 01, 2013 // By Julien Happich
Isabellenhütte has added the BVN four-terminal resistor to its range of measuring resistors. The device is 3.3 to 4mm long and has an extremely low temperature coefficient of less than 50ppm/K.

The BVN can handle continuous loads of up to 100A with a resistance value of 0.5 mOhm, and it is 25% smaller than competing resistors, claims the manufacturer. Overall, it has excellent stability over long periods and is suitable for use in a broad temperature range from -55 and 170°C. It withstands soldering temperatures of up to 350°C. The BVN can be mounted on a variety of circuit boards and substrates: it can be mounted on the traditional FR4 material used in most standard applications and on DCB ceramics for high-current applications.
