180K Ohm 2Watt Carbon Film Resistors
The 180K Ohm 2-Watt Carbon Film Resistor is part of the CFR Series, offering high performance and reliability for various applications.
These resistors are made by applying a uniform layer of pure carbon onto high-quality ceramic rods. A helical groove is then etched into the resistive layer, and tinned copper leads are welded to the end-caps. To ensure durability, the resistors are coated with a protective tan-colored lacquer.
Designed to withstand high temperatures, these resistors perform well in environments exceeding 70°C, making them suitable for demanding applications where heat resistance and stability are required.
