Power Resistor 20W 18Ω
The Power Resistor 20W 18Ω is a heavy‑duty fixed resistor designed to reliably dissipate significant power in demanding electrical and electronic applications. This component uses a wire‑wound resistive element encased in a cement‑bonded ceramic body, providing exceptional thermal stability, mechanical strength, and flame resistance that are essential for high‑load circuits. The nominal resistance of 18 Ω and 20 watt power rating allow it to handle substantial currents while maintaining performance, making it suitable for use in power supplies, industrial controls, and similar systems where high power dissipation is required.
Features:
- 20 W power rating for high‑power circuit applications.
- 18 Ω resistance with ±5 % (J) tolerance for reliable precision performance.
- Cement‑encapsulated wire‑wound construction for excellent thermal and mechanical stability.
- Through‑hole axial lead design for secure PCB mounting.
