In summary, the requirements for current sense resistors as an effective means of measuring and controlling current continue to grow. Bourns has the ability to create resistors in 1206 cases with a 10A constant current and 2512 cases with a 17A constant current. Also offered are resistors for up to 30A constant currents such as models PWR4412, PWR4413, or PWR220 with a 50A maximum constant current.
