What are the key features of RWS10 1R J?

10 W continuous power rating in a compact SMD package for high-density power circuit designs
1 Ω resistance with ±5% tolerance and ±50 ppm/°C temperature coefficient for stable sensing
Wire-wound construction provides excellent pulse handling capability above standard thick-film resistors
Surface-mount format enables automated PCB assembly in power inverters and motor control boards

What is RWS10 1R J used for?

The RWS10 1R J is used as a current-sense resistor and load element in motor drive inverters, DC-DC converters, and electronic load circuits where 10 W continuous dissipation and low resistance values are required in a surface-mount footprint. Its wire-wound construction handles high pulse energy in inrush current limiters and snubber networks better than thick-film alternatives. Industrial power supply designers rely on the ±50 ppm/°C TCR for stable current measurement accuracy across -55°C to +155°C operating temperatures.

Frequently Asked Questions

What power rating and resistance value does the RWS10 1R J provide for current sensing applications?

The RWS10 1R J is rated at 10 W continuous power dissipation with a 1 Ω resistance value and ±5% tolerance, allowing it to sense up to approximately 3.16 A continuously while generating a 3.16 V sense signal usable by overcurrent protection circuits in motor drives and power supplies.

How does the wire-wound construction of the RWS10 1R J benefit high-pulse-energy applications?

Wire-wound resistors like the RWS10 1R J have significantly higher pulse energy handling capability than thick-film SMD resistors of the same power rating, typically absorbing short-duration pulses exceeding 100 W without failure, making them suitable for inrush current limiters and snubber discharge circuits.

What temperature coefficient does the RWS10 1R J offer and why does it matter for precision sensing?

The RWS10 1R J specifies a temperature coefficient of resistance (TCR) of ±50 ppm/°C, meaning the 1 Ω value drifts by only 0.05 mΩ per °C, maintaining accurate current measurement across a broad -55°C to +155°C operating range in industrial inverters and automotive power electronics.

Can the RWS10 1R J be used in parallel to increase current capacity in a motor drive design?

Two RWS10 1R J resistors placed in parallel produce a 0.5 Ω combined resistance rated at 20 W total, allowing current capacity to scale to approximately 6.3 A continuous sensing while keeping each component within its individual 10 W thermal rating on a properly designed heat-dissipating PCB.
