Through Hole Resistors

The CMF50562K00FKEA is an example of a through hole resistor. Through hole resistors, are resistors with leads and a body that are mounted in the holes of a circuit board. They provide electrical resistance and are used in applications such as power distribution, heat dissipation, noise reduction, or impedance matching. Through hole resistors are usually made of an inert material, such as plastic, ceramic, or metal, and are designed to reduce power dissipation. The most common type of through hole resistor is the tubular type, which is made of a cylindrical body with an insulated wire running through it.

Working Principle

The working principle of through hole resistors is simple. They are designed to reduce the electrical current in a circuit by creating electrical resistance. This is done by reducing the cross sectional area of the wire running through the resistor, resulting in an increase of heat generated by the current as it passes through. Heat is generated when an electric current flows through a wire, due to the resistance of the wire. This heated area is known as the ‘Joule’s Law’.

The current passes through the resistor and is divided into two paths which generate heat as it passes through the resistor, in a process known as Joule’s Law. The resistance of a through hole resistor is determined by the material it is constructed from, the wire running through it, the physical size, and the circuit board material.

Application Field

The CMF50562K00FKEA through hole resistor is most commonly used in resistor-capacitor (RC) filter circuits and voltage-controlled oscillator (VCO) switching circuits.

In RC filter circuits, a through hole resistor along with an electrolytic capacitor is used to divide and stabilize the DC voltage output of the circuit. They are also used in VCO switching circuits to control the on and off of a voltage signal. Through hole resistors are also used for power dissipation, as they are able to dissipate large amounts of heat compared to other types of resistors.

Lastly, through hole resistors are also used as temperature sensors and are even used in RF applications to reduce signal distortion.

Conclusion

Through hole resistors, like the CMF50562K00FKEA, are used in a wide range of applications including voltage control, power dissipation, and temperature sensing. They are preferred over surface mount resistors for applications when reliability and stability are important as they are physically held in place on the circuit board. They are also preferred when larger currents are present, as their large body allows for higher wattage dissipation.
