CR75-221KC Inductors, Coils, Chokes

Fixed inductors are electronic components that are designed to work with electric current in order to create an electrical field. This electrical field enables them to store electromagnetic energy, such as AC or DC, which can be used in a variety of ways. A popular type of fixed inductor is the CR75-221KC, and this article will explore the application field and working principle of this device.

CR75-221KC Application Field

The CR75-221KC is typically used in circuit designs that require low current, high impedance, or high harmonics. Such designs might include DC-DC converters, refrigerators, and high-frequency transformers. The device is also suited for use in power converters, inverters, signal processing systems, and other electronics-related applications. The inductor can handle up to 5 amps of AC current and can operate in a temperature range of -40°C to +125°C.

CR75-221KC Working Principle

The working principle of the CR75-221KC is very simple. It works by controlling the electrical current in a circuit by creating a magnetic field around its inductive core. The device does this by using semi-conductor material, such as silicon or germanium, which are then wrapped around the inductive core. When a current is applied to the inductive core, the magnetic field generated by the semi-conductors creates an eddy current, which in turn causes a voltage to be generated in the external circuit. This voltage can then be used to control the current flow in the circuit.

Conclusion

The CR75-221KC is a type of fixed inductor, which can be used in a variety of electronic applications that require low current, high impedance, or high harmonics. Its working principle involves using a semi-conductor material to create a magnetic field around its core, which then generates a voltage in the external circuit used to control the current. This device is suitable for use in power converters, inverters, DC-DC converters, and signal processing systems, among others.
