Through Hole Resistors

Through hole resistors provide resistance in electrical circuits by converting electrical energy to heat. These resistors are also called linear resistors because their dissipation of power is linear with respect to the applied voltage.The CMF552K5690CHBF is a through hole resistor consisting of a ceramic core, aluminum oxide film, and a metallic film. It is used in high frequency circuits that require a low inductance, high current capability, and high frequency performance.

Application Fields

The CMF552K5690CHBF is a particularly versatile resistor. It is especially suited for applications where high frequency stability and a low temperature coefficient are important. It is used for frequency divisions and is suitable for a variety of video, audio, automobile, communication, and military systems. It is also commonly used in power supply circuitry, signal transduction systems, and as a passive filter for power amplifiers.

Working Principle

The CMF552K5690CHBF works by converting electrical energy to heat via the electric current passing through it. The core of the resistor is made of a ceramic material called aluminum oxide, which has a very high electrical resistance. Therefore, when a current is applied to the ceramic core, an electric field is generated and the resistance increases with increasing current. The aluminum oxide also has a very low temperature coefficient, meaning the resistance of the resistor won’t change significantly as the temperature changes. The metallic film also helps to ensure the stability of the resistor. It absorbs much of the thermal radiation emitted, resulting in a lower self-heating effect and better frequency stability.

Advantages

The CMF552K5690CHBF has many advantages over traditional resistors. It delivers high performance with its low inductance and high current capability. Also, because of its low temperature coefficient, it is able to maintain its performance in a wide range of temperatures and environments. Additionally, its low self-heating effect and conductive thermal radiation helps to reduce noise.

Conclusion

The CMF552K5690CHBF through hole resistor is an excellent choice for high frequency circuits. It is especially suited for applications where high frequency stability and a low temperature coefficient are important. It is versatile, reliable, and offers many advantages over traditional resistors.
