8k2 1/4 Watt Metal Film Resistors. 0.25 Watt 8k2 with a 1% tolerance.

Good quality Metal Film Resistors. See our Multi Buy Discount Offers on these Electronic Components.Metal Film Resistors operate at higher tempuratures.

The resistor which uses metal film to limit the flow of electric current to certain level is called metal film resistor.

 

Metal film resistor construction

The metal film resistor construction is similar to the carbon film resistor except that the material used for constructing the film is different.

In carbon film resistors, carbon is used to construct the film whereas in metal film resistors, tin and antimony or nickel chromium is used to construct the film.

 

The metal film resistor is made by placing the metal film on a ceramic substrate. The metal film resists the electric current flowing through it. Hence, it acts as resistive element to the electric current.

The ceramic substrate does not allow heat through it. Hence, it acts as insulating material to heat.

The metal film resistors are more preferred over carbon composition resistors because the metal film resistors generate less noise than the carbon composition resistors.

 

The metal film resistors have low tolerance value than the carbon composition resistors.

Metal film resistor has low temperature co-efficient of resistance

The rate at which the resistance of the material changes with change in temperature is called temperature co-efficient of resistance. Metal film resistors have low temperature co-efficient of resistance. Hence, the resistance of the metal film resistors does not change easily with change in temperature.
