RW1/RW2 Four-Terminal Current Resistors

Ohmite RW1/RW2 SMT Four-Terminal Current Sense Resistors feature extremely low resistance of 5mΩ to 50mΩ. These resistors offer high precision tolerance and low TCR of ±50ppm/°C. The modules come in a flameproof UL 94V-0 black body with white markings. Ohmite RW1/RW2 SMT Four-Terminal Current Sense Resistors operate in a temperature range of -55°C to +125°C.
