MF Metal Film Resistor, High Precision Resistor, 1/8W to 3W
Structure:
1.ZENITHSUN Metal film resistors is a thin metal layer that is sputtered (vacuum deposition) on a cylindrical, high purity, ceramic core. The deposited metal is artificially aged by keeping it for a long period at a low temperature. This results in a better accuracy for the resistor. The resistance material is often nickel chromium (NiCr), but for special applications other alloys are used, such as tin and antimony, gold with platinum, and tantalum nitride.
2.On both ends of ZENITHSUN Metal 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 MF 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 TCR: ±50ppm/℃ to 100ppm/℃
3.High Precision: ±0.1%, ±0.25%, ±0.5%, ±1%, ±2%, ±5% are available.
4.Low noise.
5.High linearity
6.Low voltage coefficient
Application:
in circuits where tight tolerance, low temperature coefficient, and low noise properties are important, ZENITHSUN metal film resistors are often used. Examples of applications are active filters or bridge circuits.
