Parts Express 100 Ohm 20W Wire Wound Resistor

SKU CH-GPET-DZRGF

Wire-wound resistor rated at 100 ohms and 20 watts with 10% tolerance, sold individually

  • TypeResistors
  • 20 W power rating handles demanding circuits
  • 100 Ω resistance value for precise applications
  • Wire-wound construction ensures stable performance
  • 10 % tolerance supports accurate designs
  • Single resistor sold individually for flexible ordering

Component Identity

This is a single wire-wound resistor rated at 100 ohms and 20 watts with a 10% tolerance. It suits hobbyists, technicians and engineers building or repairing power supplies, amplifier circuits or test loads where a robust through-hole power resistor is required.

Construction and Leads

The wire-wound element handles sustained heat better than carbon or metal-film types, making it reliable for continuous dissipation. Axial leads allow straightforward through-hole mounting on perfboard or PCBs without special footprints or surface-mount equipment.

Deciding Specification

The 20 watt power rating is the critical figure; circuits demanding higher continuous dissipation will exceed this part's safe limit. Buyers needing lower power ratings or tighter tolerances should select a different component.

Highlights

  • 20 W power rating handles demanding circuits
  • 100 Ω resistance value for precise applications
  • Wire-wound construction ensures stable performance
  • 10 % tolerance supports accurate designs
  • Single resistor sold individually for flexible ordering
