Fixed inductors are passive electronic components, comprising of wires wound together in a coiled pattern around a central core. They are used to limit the flow of signal in a circuit. The PM5022S-680M is a fixed inductor developed by Panasonic and is used to protect circuit from high power transients and over voltage conditions. The key components are two wound coils, an outer one in a soft ferrite core, and an inner one in a hard ferrite core. It is a two-layer construction with an air gap between the two layers.

Application Field

PM5022S-680M inductors are designed for use in switching power supplies as they provide a good peak current rating and hold very high power handling. The inductors have a high power rating and are able to withstand high voltages and current transients, making them suitable for a range of applications, including power converters, DC/DC converters, LED drivers, power amplifiers and high current supplies. The highly reliable and robust design also makes it ideal for use in a variety of communication systems.

Working Principle

The working principle of PM5022S-680M inductors is based on the idea that the current will resist any sudden change in the applied voltage. This means that when a voltage is applied, only a small amount of current will flow. The PM5022S-680M inductor is designed with an air gap between the two layers of the coils. This air gap increases the inductance which decreases the current flow when a voltage is applied. In addition, the high power rating of the inductor makes it suitable for handling higher power levels and transients. The ferrite material of the coil also makes the inductor suitable for high frequency applications.

The PM5022S-680M inductor also has low DCR (DC resistance), which makes it highly suitable for power conversion. This low DCR is achieved by using high quality materials for the core and coil windings, allowing for higher efficiency and reliable operation. The inductor also has a wide operating temperature range, making it suitable for use in a variety of environments.

Conclusion

The PM5022S-680M inductor is a high-performance fixed inductor developed by Panasonic. It is designed to handle high power and transients, making it an ideal choice for a range of power applications. It has two layers of coils wound together in a ferrite core, with an air gap between the two layers. This increases the inductance while the low DCR provides higher efficiency. The inductor also has a wide operating temperature range, making it suitable for use in a variety of applications.
