With the BVF, Isabellenhütte Heusler has developed a precision resistor that not only offers a unique size 1213 (3,1 x 3,3 mm), but also an extremely high load capacity and precision. Smaller electrically operated applications in particular benefit from the properties of the high-performance component that the manufacturer has now added to the series repertoire.
The temperature coefficient of the precision resistor BVF is below 70 ppm / K. The thermal resistance is also extremely low at 10 K / W. This results in the high load capacity of the BVF of 3 W at a temperature of up to 145 ° C at the contact point. Due to the robust construction in the "ISA-Weld" technology, the component is suitable for a temperature range from -65 ° to +175 ° C and is thus above the currently required limits for typical automotive applications.
Flexible all-rounders: DC motor with and without brushes
The BVF is qualified according to AEC-Q200. The BVF is used, for example, in electric vehicles and e-scooters, but also in air conditioning systems and washing machines. Basically, it can be used in all applications that involve brushless DC motors operate. The BVF shunt sits in a module that has one BLDC motor drives. The shunt is installed in power modules that control these motors.
