Fixed inductors are passive components that store energy in the form of a magnetic field. They are used in many electronic circuits, and CR75NP-100KC is a common type of fixed inductor. It provides a stable inductance value and is suitable for a wide range of applications.

Applications

CR75NP-100KC is used in a variety of applications, including power line filters and transformers, RF circuits, switching power supplies, voltage regulator circuits, and high-frequency antenna circuits. It can also be used in communication systems, including telephone and broadband systems.

In a transformer, the CR75NP-100KC provides the inductance required for the primary winding to generate a magnetic field. This magnetic field then induces a current in the secondary winding, and so is used to increase or decrease the voltage in the circuit.

It can also be used in filter circuits to reduce noise. Filter circuits are used to reduce noise in power supplies and protect sensitive components from voltage spikes or transients. The CR75NP-100KC provides the inductance that allows the filter to reduce the noise.

Operating Principle

The CR75NP-100KC fixed inductor works on the principle of electromagnetic induction. When a current is applied to the winding, a magnetic field is generated around the core, and this magnetic field induces a voltage in the winding. This induced voltage opposes the applied voltage, reducing the current. The amount of opposition can be adjusted by adjusting the inductance of the winding.

The inductance is adjusted by changing the number of turns, the core material, and the core shape. Increasing the number of turns increases the inductance, and using a core material with a higher relative permeability increases it further. Changing the core shape to reduce the air gap also increases the inductance.

The power dissipated in the core is a function of the core material’s properties and core temperature. Ceramic cores are generally not used in high-power applications because the temperature of the core can increase significantly when a large current is flowing, resulting in decreased performance. Iron-cored inductors are the best choice for high-power applications.

Conclusion

The CR75NP-100KC is a versatile fixed inductor that is well suited for a variety of applications. It is designed to provide a stable inductance value, and its operating principle is based on the principle of electromagnetic induction. It can be used in transformers, RF circuits, filter circuits, power supplies, and many other types of circuits.
