Wirewound Resistor

Wirewound Resistors can range from small surface-mount components to large, tubular (and even heat-sinkable) power resistors. They are typically used in high-current applications. Applications for Wirewound Resistors include current sensing, snubber circuits, dynamic braking, current and/or voltage balancing, and as a “bleed resistor”. Wirewound Resistors can have either a small or a large Temperature Coefficient of Resistance (TCR), and are also available in many tolerances and power levels. Richardson RFPD provides design support to help engineers select the best Wirewound Resistor for the specific application. Specific attributes which are important in selecting the right Wirewound Resistor for your application include: Package Type – usually Axial, Heat Sinkable, Radial, SMD, or Tubular; Maximum Voltage Rating (V); Power Rating (W); Resistance (Ω); Tolerance (%); Operating Temperature Range (⁰C); Temperature Coefficient (ppm/⁰C); and the part’s Dimensions (mm).
