Through Hole Resistors – CMF55453R00FKEA Application Field & Working Principle

Through hole resistors are key components in electrical engineering, telecommunications, industrial, and automotive systems. They are utilized to control current flow within circuits, providing electrical stability and attributing to desired outputs. One example of a through-hole resistor is the CMF55453R00FKEA. This is a high-power ceramic resistor package molded into a single-thick-film-resistor shield with laser-cut lead wire terminations. This resistor is suitable for currents up to 25 amps and it is capable of withstanding differential temperature stress of up to −55 degree Celsius to 175 degree Celsius. This makes the CMF55453R00FKEA ideal for high-temperature electronic applications, as well as power supplies and control circuits.

General Working Principle

The CMF55453R00FKEA has a working principle that is similar to other through-hole resistors. When a voltage is applied across the package, the resistance of the resistor material begins to decrease, allowing current to pass through. For a fixed voltage, the current flow depends heavily on the resistance of the resistor material. The structure of the CMF55453R00FKEA also helps to reduce interference and noise in the circuit. The thick-film-resistor shield material acts as a barrier, preventing the signals from passing through to the other components. This helps to cut down on crosstalk, as well as shielding the internal components from outside noise.

Visual Structure

The CMF55453R00FKEA has an extremely simple and compact design. It consists of a flat, rectangular ceramic body molded around lead wires that are cut into a curved shape at the ends. This shape forms a circular shape, which helps to hold the lead wires in place and prevents them from being pulled out of the body. It also helps to dissipate heat more efficiently. The resistor element is located on the inner side of the ceramic body in order to provide better protection from external factors such as shock and vibration. It also helps to shorten the path of the circuit and minimize interference. Moreover, the lead wires are electrically insulated by a thick-film-resistor shield, which increases stability and long-term reliability.

Application Areas

The CMF55453R00FKEA is most often used in power supplies and control circuits for electronic applications. This type of resistor is suitable for high-current applications due to its high-temperature rating and its resistance to differential temperature stress. It is also used in telecommunications systems and automotive applications due to its simple structure and high-interference protection. Moreover, it is suitable for use in low-load circuits, as well as high-power applications. This type of resistor is capable of operating at high power levels, while still maintaining a low resistance value, making it suitable for applications where current needs to be precisely controlled.

Conclusion

The CMF55453R00FKEA is a high-power ceramic resistor package that is designed to be used in high-temperature electronic applications. It is composed of a thick-film-resistor shield to protect the internal components from external noise, as well as a laser-cut lead wire terminations. The package is suitable for currents up to 25 amps and it is capable of withstanding differential temperature stresses of up to −55 degree Celsius to 175 degree Celsius. The CMF55453R00FKEA is ideal for power supplies and control circuits, and it is also suitable for use in telecommunications and automotive systems.
