Working Principle

Fixed inductors, such as the PM0402-39NJ, work on the principles of electromagnetic induction. When an alternating current flows through the coil of an inductor, it creates a magnetic field. This magnetic field stores energy, which is then released back into the circuit when the current is changed. The amount of energy stored is proportional to the inductance of the coil, and thus, the amount of voltage dropped across the device. This is what allows fixed inductors to act as voltage regulating components in an electrical circuit.

The PM0402-39NJ is a high inductance, low profile inductor, designed to optimize voltage regulation in high current applications. The unique construction of the PM0402-39NJ allows for high current carrying capabilities, up to 16.7A, while requiring minimal space. The device is available in a variety of termination configurations, and can be used in a variety of circuit applications, such as switched-mode power supplies and DC/DC converters, as well as other general signal filtering and voltage regulation applications.

Conclusion

The PM0402-39NJ is a high current, low profile surface-mount inductor, designed for use in high current applications with supply voltages up to 32V. The device is optimized for use in switched-mode power supplies and DC/DC converters, and is suitable for use in noise suppression, compensation for line-frequency, space-saving control circuit, and multiple winding applications, as well as in other general signal filtering or voltage regulation applications.
