CSM5930A High Power Current Sense Resistors
CSM5930A resistors from VPG Foil Resistors are ideal for current monitoring in automotive, power management, industrial, and communication systems
CSM5930A high-performance two-terminal current sense resistors from VPG Foil Resistors are engineered for power applications requiring precision, reliability, and minimal resistance. Constructed with a metal strip design and proprietary processing, the CSM5930A achieves resistance values as low as 0.1 mΩ while supporting continuous currents up to 387 A and power ratings up to 15 W at +70°C.
With a temperature coefficient as low as ±50 ppm/°C and tolerance options down to ±1%, this resistor delivers dependable performance in harsh thermal environments from -65°C to +170°C. Their low inductance design (<3 nH) and AEC-Q200 qualification make them ideal for current monitoring in automotive, power management, industrial, and communication systems.
