Power wirewound SMD resistors range from R005 to 50k
The resistors’ 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 series of resistors are 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 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 the model.
