Through Hole Resistors

Through hole resistors, especially CMF55205K00BEBF, are a kind of component widely used in various type of circuits. It houses within an axial leaded package and allows axial leaded mounting. Such resistors are best suited for applications such as switching circuits, switching frequency circuits and wide frequency range circuits.

Original Design

The CMF55205K00BEBF is the original design developed by Murata, using the even-spaced lead frame arrays technique and a special waxed packaging. It is designed to a maximum temperature of 85 degrees Celsius and a maximum capacity of 5 watts. The resistor element used is made of a metal film coating, specially developed for this type of component. The resistors are designed to offer low power dissipation, low noise and fast dynamic response.

Application Field and Working Principle

The most common application field for a CMF55205K00BEBF is for the switching of power stages in a variety of circuits. It is also used in frequency and time dependent circuits to provide reliable current control. The principle of operation for the resistor is based on Ohm\'s Law, such that the voltage applied across the resistor will cause a current to flow, the magnitude of which is dependent on the size of the resistor. By modulating the size of the resistor, the current in the circuit can be regulated.

The resistor\'s element is constructed using a metal film coating, which behaves as an insulator and prevents the flow of current when operated under the specified temperature profile. This behavior is due to the expansion of the metal film coating causing an increase in the distance between the contacts resulting in insulating properties. Therefore, the resistor must be operated within a specified temperature range to maximize its performance.

The resistor also features a back termination that allows it to be mounted in the circuit board in reverse direction, which further reduces the current flow in the circuit making it suitable for multiple tasks. Furthermore, the resistors feature excellent mechanical and environmental characteristics, making them ideal for use in industrial applications.

Conclusion

In conclusion, the CMF55205K00BEBF through hole resistor is an ideal component for switching of power stages in a number of applications. Its fast and dynamic response times make it suitable for fast switching circuits. Its special axial-leaded package results in low power dissipation and therefore better protection against short-circuit and overloads. Moreover, its back termination allows mounting of the resistor in reverse direction to achieve lower current flow. All these features make it an essential component for various types of circuits where current and power level needs to be precisely regulated.
