Fixed Inductors

Fixed inductors are essential components in many types of electrical and electronic circuits. They are typically used for power line filtering, blocking, coupling, noise suppression, and managing transient voltages. In this article, we will discuss the application field and working principle of B82144B2124J000, a fixed inductor manufactured by EPCOS.

Construction

The B82144B2124J000 is a 0.102µH shielded fixed inductor. It has a ferrite core wrapped with a copper wire winding and is capable of operating at temperatures up to 125°C. It also has a high saturation current rating of up to 40A, along with a rated voltage of 200V. The size of the inductor is only 9.3mm x 10mm, making it small enough to fit into a variety of applications.

Application Field

The B82144B2124J000 inductor is commonly used in switch mode power supplies (SMPS) and other power management products. It is designed to provide good thermal performance and high current capabilities, making it ideal for automotive and digital home applications where size restrictions and high operating temperatures are a concern. It is also suitable for power factor correction (PFC) circuits and resonant DC-DC converters.

The B82144B2124J000 is also widely used in high frequency DC-to-DC resonant switching converters. It is able to operate up to 4MHz, and its high current rating allow it to handle high value currents in noisy environments.

Working Principle

The working principle of an inductor is based on its construction. An inductor is a device made from a coil of wire, usually with a ferrite or another magnetic core inside it. When electric current passes through the coil, it creates a magnetic field that stores energy. When the electric current changes direction, the magnetic field also changes, and this induces an electromotive force (EMF). This EMF opposes the change in current and creates resistance in the circuit.

The B82144B2124J000 has a very high inductance rating, meaning it can store a lot of energy and produce a significant amount of back EMF in order to oppose changes in current. Its high current rating means it can handle currents up to 40A without overheating. Its shielded construction prevents any interference from external sources, making it ideal for noisy environments. This makes the B82144B2124J000 an ideal choice for a wide range of applications.

Conclusion

The B82144B2124J000 fixed inductor is a versatile and reliable component suitable for a wide range of applications. Its construction allows it to handle high current without overheating, and its shielded construction helps to protect it from external interference. Its high inductance rating and high saturation current rating make it ideal for power line filtering, blocking, coupling, and noise suppression. With these properties, the B82144B2124J000 is a great choice for use in automotive, digital home, and power management applications.
