Fixed Inductors

Fixed inductors, also called choke coils and line inductors, are electronic components used in electrical circuits to store energy in the form of an electromagnetic field. Fixed inductors are typically used in applications where a high reactance value is desired to limit the flow of current such as power supplies, filters, and oscillators. They are also used in audio signal applications and other high frequency switching circuits.

CDRH127/LD-220MC Application Field and Working Principle

The CDRH127/LD-220MC is a compact, high performance, shielded power Inductor designed for use in switch-mode power supplies, power converters, and various filtering applications. The CDRH127/LD-220MC is a cylindrical-shaped inductor with a winding of iron powder core, in which a single layer of insulated wires are wound. This winding serves to increase the inductance of the circuit. The device is able to operate in power ratings up to 20 Amps and temperatures up to 115°C and maintain high performance characteristics including excellent power distribution throughout its operating temperature range.

The device can be used in a variety of applications such as high-frequency DC/DC converters, AC/DC converters, and power supplies. The device has a number of advantages, including a very low DCR and a wide range of operating frequencies. The device has a high operating temperature range and can handle a variety of ripple and noise levels. In addition, the device has a verified thread vibration test, a verified autoclave soak test and a verified reflow temperature range.

The design of the CDRH127/LD-220MC allows it to perform its primary purpose—to reduce the power ripple of the circuit under large changes in voltage. This is achieved by connecting the inductor in parallel with the power source, so that when the circuit experiences a decrease in voltage, the inductor\'s increasing inductance opposes the change and stores energy. When the voltage increases, this stored energy is then released, resulting in a decrease in power ripple. This type of circuit is known as a buck converter.

In addition to its use in buck converters, the CDRH127/LD-220MC can also be used in series circuits and in high frequency applications. In a series circuit the inductor\'s resistance will decrease as the frequency increases, allowing the device to act as a low-pass filter. When used in high frequency applications, the CDRH127/LD-220MC can be used as an impedance transformer or a high-pass filter.

Conclusion

The CDRH127/LD-220MC is a compact, high performance, shielded power Inductor designed for use in switch-mode power supplies, power converters, and various filtering applications. It features a very low DCR, a wide range of operating frequencies, a high operating temperature range, and can handle a variety of ripple and noise levels. The device can be used in both buck converters and series circuits and is also suitable for use in high frequency applications such as an impedance transformer or a high-pass filter. The device has a number of advantages, including excellent power distribution throughout its operating temperature range.
