Ohmite RVK 4-Terminal Metal Alloy Current Sense Resistors
Ohmite RVK 4-Terminal Metal Alloy Current Sense Resistors offer low resistance of 0.5mΩ to 6mΩ and a low temperature coefficient of resistance (TCR) of ≤+50ppm/°C. The 4-terminal design of these Ohmite resistors allows for 0.5% resistance tolerance down to 0.0005Ω. The RVK series provides high-current sensing, excellent long-term stability, and a wide operating temperature range of -55°C to +170°C. Applications include power supplies, measuring instruments, industrial, and battery management systems (BMS).
