Precision power wirewound resistor is surface mountable
Designed to meet rising power requirements for surface mount components, the devices optimised thermal design is targeted to give greater efficiency and improved surge capacity of up to 5 times for 5 seconds, whilst reducing surface temperature rise compared with other resistors. The RWS range provides excellent overload characteristics, good stability, low standard TCR and low inductance and custom versions are available if required.
The RWS series of resistors are wirewound, constructed on an alumina core with steel end caps. The body is an encapsulated epoxy moulded compound with thermo conductivity contours.
Typical applications include shunt resistors, power supply current sense, capacitor discharge and bleeder resistors.
The RWS series offers high reliability and has been engineered to reduce long term thermal damage to printed circuit boards and surrounding components. RWS series resistors are RoHS compliant and available in low inductance format and with close TCR and standard tolerance of 0.5%, 1% and 5%. The operating temperature range is – 55°C to +155°C or + 275°C depending on model.
The ARCOL RWS resistor series offers an ohmic range from R005 to 50 KΩ at power ratings from 0.05 to 50 KΩ at 5 W, R1 to 5 KΩ at 7 W and up to 10 K at 10 W.
