ZENITHSUN Carbon Fixed Film Resistor 22MΩ 1/8W to 5W Bulk Package

Formed 1/8W to 5W Carbon Film Fixed Resistor,bulk package


Structure:

1.ZENITHSUN carbon film resistor is a thin carbon layer that is sputtered (vacuum deposition) on a cylindrical, high purity, ceramic core.The deposited carbon film is artificially aged by keeping it for a long period at a low temperature. This results in a better accuracy for the resistor.
2.On both ends of carbon film a metal cover is pressed with the connection leads.
3.The desired resistance is achieved by cutting a spiral shaped slot in the thin metal layer.
4.ZENITHSUN CF resistor is covered with several coating layers that are baked individually. The coating protects against moisture and mechanical stresses.
5.The resistor value is marked by color code bands.


Feature:

1.Reliability.
2.Low capacitance
3.Low inductance, good high frequency performance.
4.Low noise.


Application:

The typical uses for ZENITHSUN carbon film resistors are in high voltage and high temperature applications. Operating voltages up to 15 kV with a nominal temperature of 350 °C are feasible for carbon film resistors.. Example uses include high voltage power supplies, radars, x-rays, and lasers.
