What is a metal film fixed resistor used for?
A resistor is an electronic component that restricts the flow of electrical current in a circuit, thus controlling the flow of energy. A metal film fixed resistor is a type of resistor that is made up of a thin metallic film layer coated on a ceramic or glass rod.
What is a Metal Film Fixed Resistor Used For?
Are you curious about how electronic devices work? Then, you must have heard about the essential component in these devices called resistors. One type of resistor, the metal film fixed resistor, is often used in electronic circuitry. In this article, we will discuss what a metal film fixed resistor is and its uses in different applications.
What is a Metal Film Fixed Resistor?
A resistor is an electronic component that restricts the flow of electrical current in a circuit, thus controlling the flow of energy. A metal film fixed resistor is a type of resistor that is made up of a thin metallic film layer coated on a ceramic or glass rod. The metallic layer's thickness measures less than 1% of the overall resistor, which provides precision and stability for the process.
Uses of Metal Film Fixed Resistor in Electronic Devices
Apart from the fundamental function of resisting the flow of electrical current, Metal Film Fixed Resistors can also perform several other functions. Let's take a look at some of the main applications of this type of resistor.
1. Voltage Divider
Voltage dividers are circuits used to divide a voltage source into smaller parts. The metal film fixed resistor is the most common type of resistor used for this application. Voltage dividers are essential in applications where voltage levels need to be adjusted in electronic components.
2. Amplifiers
Amplifiers are electronic circuits that amplify the voltage or current of a signal. Metal film fixed resistors are used in pre-amplifier circuits, where the input signal needs to be attenuated before amplification. They are also used in the feedback circuit of amplifiers, where the output signal needs to be subtracted from the input signal.
3. Oscillator Circuits
Oscillator circuits are used to generate a stable frequency signal. Metal film fixed resistors provide accuracy for the oscillator circuits, making them ideal components for this application.
4. Snubber Circuits
Snubber circuits are designed to deal with inductive and capacitive surges in electronic circuits. Metal film fixed resistors are used in snubber circuits, alongside capacitors and inductors, to absorb energy surges that would otherwise damage the electronic components.
