Applications requiring power control and monitoring are becoming more demanding. Specifically, added functionality and higher power requirements require higher efficiency, high accuracy, and higher power handling. Products that only required a 1 or 2W current sense resistor in the past may now desire a 3, 4, or 5W device. Resistor TCR of 200 or 300 ppm may no longer be adequate.
Stackpole’s CSRF2817 foil on ceramic current sensing chip resistor offers a power rating of up to 5W and resistance values of 5, 6, 8, 10, 15, 20 and 33 milliohm. TCR for these values is 50 ppm and available tolerances are 1% and 5%.
Applications include a wide range of power supply types, motor controls, industrial controls, voltage regulators, and LED drivers.
Pricing varies with tolerance, and resistance and ranges from $0.275 to $0.35. Contact Stackpole or one of our franchised distributor partners for volume pricing.
