100K Ohm 1Watt Carbon Film Resistor (Pack of 100)

100K Ohm 1Watt Carbon Film Resistor

The CFR Series Carbon Film Resistors are produced by applying a uniform layer of pure carbon onto high-quality ceramic rods. A helical groove is then carved into the resistive layer, and electrolytic copper leads are welded to the endcaps. To protect against environmental factors, these resistors are coated with multiple layers of tan-colored lacquer. This construction guarantees optimal performance and durability, even in conditions where ambient temperatures exceed 70°C.

How to Use 100K Ohm 1Watt Carbon Film Resistor

Position the resistor leads into your PCB or breadboard according to your schematic, ensuring enough lead length for solder joints or secure insertion. Since carbon film resistors are non-polar, orientation does not matter—just confirm the 100KΩ value by its color bands before soldering and allow adequate spacing to dissipate heat under load.

Frequently Asked Questions

What does the brown-black-yellow-golden color code indicate?

The first two bands (brown, black) denote “10,” the third band (yellow) adds four zeros, giving 100,000 Ω, and the gold band signifies a ±5% tolerance.

What is the maximum current this resistor can handle?

At its 1W power rating and 100KΩ resistance, the resistor’s maximum continuous current is approximately 3.162 mA; exceeding this may overheat the component.

Can I use these resistors on a breadboard for prototyping?

Yes. The tin-plated copper leads fit standard breadboard holes securely and can also be soldered directly onto PCBs for durable installations.
