Through Hole Resistors

Through hole resistors are components commonly used in electronics to regulate the flow of current within a circuit board. The CMF554K4700BEEB is an example of a through hole resistor that can be used in many types of electronic applications.

Applications

The CMF554K4700BEEB is a 0.5W, 5% tolerance through hole resistor commonly used in a variety of applications. It is usually used for general purpose applications such as power supplies, motor control, lighting control, and audio. Due to its small size and low cost, the CMF554K4700BEEB is widely used in consumer electronics, such as television and radio receivers, industrial control boxes, and even telephone equipment.

Operation and Working Principle

The CMF554K4700BEEB is a non-linear resistor that works by providing a resistance to the flow of electricity in a circuit. This resistor allows certain amounts of current to pass through it depending on the amount of voltage applied to it. The resistance of the resistor is determined by its size, shape, and material.

The CMF554K4700BEEB is made of a ceramic-encapsulated substrate containing a highly conductive metal oxide layer. This layer has an interface with the substrate which forms a thin barrier of resistive material that limits the current flow. When a voltage is applied across the CMF554K4700BEEB, a resistive layer is formed between the metal oxide layer and the substrate. This layer creates an electric field which will resist the flow of electric current.

When a circuit includes more than one CMF554K4700BEEB, the current passing through each one is determined by the total resistance of all the resistors in the circuit. This total resistance is determined by the resistance of each resistor, and the number of resistors in the circuit.

Testing

When testing the CMF554K4700BEEB, it is important to use an ohmmeter to ensure the correct resistance is present to prevent any major problems with the circuit. Testing the CMF554K4700BEEB is a straightforward process, that simply requires connecting the ohmmeter leads to each end of the resistor and measuring the resistance. The measured resistance should match the resistor’s markings. If the resistance readings are not accurate, the resistor might need to be replaced.

Conclusion

The CMF554K4700BEEB is a 0.5W, 5% tolerance through hole resistor commonly used in a variety of applications. It is made of a ceramic-encapsulated substrate containing a layer of highly conductive metal oxide which produces a resistive layer when exposed to a voltage. When testing the CMF554K4700BEEB, it is important to use an ohmmeter to ensure its resistance is accurate.
