Caddock and A J Distributors have announced that the Model SR20 is now available in resistance values as low as 0.005 ohm (5 milliohm) for continuous currents up to 20 Amps.

The SR20 is a non-inductive precision current sense resistor designed for industrial and commercial current sensing applications including: power supplies, battery chargers and monitoring, motor and motion control, industrial automation, solar power current monitoring and other current sensing applications.

The SR20 features Kelvin (4-wire leads) for accurate 1% performance.

The compact footprint uses little board space, but operates cool for outstanding stability.

• Non-inductive design
• Resistance values from 0.005 ohm to 1.00 ohm +/-1%
• Kelvin (4-wire) leads
• Compact footprint
• Power rating 2 Watts at 70°C ambient
• Cool operation and outstanding long-term stability
