RWS Series SMD Resistors set new standards

ARCOL’s RWS Surface Mount resistors have been designed to meet the needs of the ever-increasing power requirements of resistors in surface mount applications.

Rated at 10W the RWS10 is the highest-power SMD resistor on the market today. The RWS7 is rated at 7W.

The ARCOL RWS resistors provide excellent overload characteristics with a surge capacity of up to 5 times rated power for 5 seconds, ±(0.5% + 0.5mΩ) ΔR. Again this is better than any other SMD resistor currently available.

The thermal design has been optimised to provide a greater heat-reduction efficiency, resulting in a lower surface temperature rise, when compared with other (lower power) SMD resistors on the market.

The ARCOL RWS resistors also have excellent stability and TCR characteristics: ±90ppm/°C R1 – R99, ±50ppm/°C 1R – 10R, ±20ppm/°C > 10R.

Low inductance is available. The operating temperature range is -55°C to +275°C and the maximum working voltage is (PxR) ½.

The new RWS Power Resistors are RoHS compliant and are designed for easy assembly.

The Life specifications have been measured at a Test temperature of 70˚C ±2˚C, with a rated DC continuous working voltage applied, 1.5 hours on and 0.5 hours off for 1000 hours, ±(2.0% +0.5mΩ)ΔR.
