Edge Wound Resistor
Description
Edge wound resistors can dissipate very high energy pulses in short time. They are used for low ohmic values. There are 2 families RNT and RNP, but it’s possible to customize them.
ERPL is an indian manufacturer and supplier of edge wound resistor which is a specialized type of high-power resistor designed to handle significant electrical loads and dissipate heat efficiently. It is constructed by winding a resistive wire along the edges of a ceramic core, resulting in a compact and robust structure. This unique configuration maximizes the surface area, enhancing heat dissipation capabilities. Edge wound resistors are commonly used in demanding applications, such as power distribution, motor drives, industrial machinery, and high-frequency circuits. Their ability to withstand high temperatures and maintain stable resistance values makes them indispensable components for high-performance electronics, ensuring reliable and safe operation in critical systems.
Construction
Aluminium housed Resistor are wound with NickelCopper or Nickel Chromium wire for obtaining required resistance on a ceramic core fitted with end caps. The winded assembly is then encapsulated in a anodised Heat sink using high temperature moulding compound.
