Fixed inductors use a core material of copper, ceramic, ferrite, or iron powder. This core material is then wound with wire to create an inductor. The PM428S-121-RC fixed inductor is designed to be used in automotive, consumer, industrial, and communications applications. The PM428S-121-RC also serves as a high power core inductor and works well with both low and high frequency applications.

Introduction

Fixed inductors are inductors that are designed to generate a magnetic field with a certain amount of resistance and same rate of inductance. They are commonly found in consumer electronics such as laptop computers, radios, and televisions. This type of inductor has become more popular due to its small size and high power handling capacity. The PM428S-121-RC fixed inductor is a great choice for applications requiring high power while maintaining reliable performance.

Application Field

The PM428S-121-RC fixed inductor is designed to be used in automotive, consumer, industrial, and communications applications. The inductor is well suited for both low and high frequency applications and is designed with a low profile for better heat dissipation. It is also well suited for use in power systems, DC-DC power converters, voltage regulators, motor drive circuits, and power amplifiers.

The PM428S-121-RC fixed inductor has a maximum inductance of 121nH and can handle up to 4 amps of current at peak current. The inductor is specified to have an inductance tolerance of ±20%. These specifications make the PM428S-121-RC an ideal choice for automotive and consumer applications requiring high power handling and reliability.

Working Principle

The PM428S-121-RC fixed inductor works on the principle of electromagnetic induction. It is composed of a coil of wire wound around a magnetic core material. When current is passed through the wire, a magnetic field is generated around the wire which induces a current in the coil. This induced current is known as an electromagnetic field which is generated by the passing of the electrical current.

The inductor’s ability to generate the electromagnetic field is determined by its inductance which is defined as the amount of electromotive force (EMF) generated per ampere of current. The higher the inductance, the stronger the magnetic field and the more electrical current is generated.

The PM428S-121-RC fixed inductor has a good power dissipation rating of 150mW and requires a minimum mounting height of 16.00mm. The inductor also features a high maximum peak current of 4.00A and a wide operating temperature range of -55°C to +125°C.

Conclusion

The PM428S-121-RC fixed inductor is a valuable asset to any electronic device due to its ability to efficiently handle high power applications while maintaining reliable performance. The inductor is well suited for automotive, consumer, industrial, and communications applications due to its small size and compatibility with both low and high frequency applications. The PM428S-121-RC also features a low profile for better heat dissipation, a high peak current rating of 4.00A, and a wide operating temperature range of -55°C to +125°C. Overall, the PM428S-121-RC fixed inductor is an ideal choice for high power applications.
