Fixed inductors are electrical components that maintain a stable inductance value over a range of current and frequency. The PM7032S-220M is a fixed inductor that has a construction specifically designed to meet the needs of a variety of different applications. In this article, we\'ll take a look at the application fields and working principle of the PM7032S-220M.

Applications and Design Features of the PM7032S-220M

The PM7032S-220M is suitable for a wide range of applications, including dc-to-dc converters, power factor correction inductors, step-down converters, and others. It has a small size and low profile which makes it ideal for space-constrained applications. The inductor itself measures 7.00 x 3.30 x 4.60 mm, while the coil is tightly wound on a green core material to provide better core retention, vibration resistance, and improved performance. The core material is also equipped with a yellow adhesive strap, which increases the inductor\'s overall stability and shielding properties.

The PM7032S-220M also has a relatively low DCR of 0.11 ohms, and a high inductance of 220 uH. Its ESR is also relatively low, making it an ideal choice for high switching frequency applications. It also has a maximum saturation current of 12 A and a rated current of 10 A, making it suitable for high current applications.

Working Principle of the PM7032S-220M

The PM7032S-220M is a type of fixed inductor which operates on the principle of Faraday\'s law of induction. According to the law, a changing magnetic field will induce an emf in a nearby circuit. In the case of the PM7032S-220M, the emf is created by a current passing through a coiled conductor. The strength of the induced emf is determined by the number of turns of the coil, the current flowing through the coil, and the strength of the magnetic field.

The PM7032S-220M is designed to maintain its inductance value over a range of current and frequency. This is achieved by the tightly wound coil and the use of the green core material, which provide an effective inductor core. The construction of the PM7032S-220M also leads to an improved shielding and vibration resistance, as well as a lower ESR.

Conclusion

The PM7032S-220M is a type of fixed inductor that is suitable for a wide range of applications, including dc-to-dc converters, power factor correction inductors, and step-down converters. It has a small size and low profile, as well as a low DCR and ESR. Its working principle is based on Faraday\'s law of induction, and its construction provides improved shielding, vibration resistance, and improved performance. In conclusion, the PM7032S-220M is an ideal choice for high current, high switching frequency applications.
