Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
The BKW 4-terminal current sensing precision shunt resistor series from Isabellenhütte has been designed for use in energy meters and other battery management and current sensing applications. These resistors are qualified for 20A, 40A, 60A and 80A energy meters. The BKW series is available with resistance values from 0.0003Ω to 0.0005Ω as well as excellent long-term stability, meaning energy meters do not require any recalibration. Other benefits include very high reproducibility of R-value and TCR.
