 BVN four-terminal resistor

Isabellenhütte has announced the BVN four-terminal resistor that boasts a small size between 3.3mm and 4mm and an extremely low temperature coefficient of less than 50ppm/K. According to the company, the BVN can handle continuous loads of up to 100A with a resistance value of 0.5mΩ.

Overall, it has excellent stability over long periods and is suitable for a broad temperature range between -55°C and 170°C as well as for soldering temperatures of up to 350°C. The BVN can also 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.

The BVN is intended for numerous automobile and industrial applications such as frequency converters in drive technology and power modules in inverters, as measuring resistor in power hybrids, and for high-current applications in automobile technology. The components are ideally suited to use on ceramic substrates thanks to their excellent thermal-cycling resistance and the minimal footprint in high-current applications (control electronics, e.g. power steering), added the firm.
