Product Overview
The RC55Y-4K99BI is a 4.99kΩ 250mW through-hole mounting precision Metal Film Resistor with solder-coated copper wire terminations. A metal film is deposited onto a high quality ceramic former. Nickel-plated steel caps are force fitted to the former and termination wires are welded to the caps. The resistor is adjusted to value by a helical cut in the film and the body is protected with a specially formulated epoxy coating. The body protection and marking is resistant to all normal industrial cleaning solvents suitable for printed circuits.
- Low noise and negligible voltage coefficient
- Solder coated copper wire
