Introduction to 4379-562JS

Fixed inductors are a type of electrical component primarily used to control electrical current by providing a level of impedance to an electrical circuit. The 4379-562JS fixed inductor is designed for use in automotive and power applications that require high current operation. It is a shielded 29.9µH inductor with a current rating of up to 1.0A, a saturation current rating of up to 3.0A, and is rated for operating temperatures up to 125°C.

Design Features of 4379-562JS

The 4379-562JS fixed inductor is a Shielded Ferrite Core inductor with an epoxy encapsulated terminal design. It has a ferrite core material with a copper coil winding that is composed of a enameled copper wire with a round cross section. The inductance is rated at 29.9µH with a tolerance of ±16% and a Q factor of 25 that is typical. This inductance value is static and it is not frequency dependent. The inductor has a current rating of up to 1.0A and a saturation current rating of up to 3.0A. The 4379-562JS has an environmentally friendly design with lead-free terminals. It has an operating temperature range of -55 to +125°C and a storage temperature range of -55 to +150°C, making it suitable for use in a wide range of applications. The epoxy encapsulated terminal design also provides superior insulation with a dielectric strength of 700VAC and a surge current capability of up to 400 amperes.

Applications of 4379-562JS

The 4379-562JS fixed inductor is suitable for applications in the automotive and power electronics industry that require high current operation. It is an ideal choice for use in DC/DC converters, power supplies, Inverters, motor drives, and other industrial applications. It is also suitable for applications in the telecoms market, such as base station and data center power supplies.

Working Principle of 4379-562JS

The 4379-562JS fixed inductor works on the principle of electromagnetic induction. When an alternating current passes through the coil of the inductor, an electric field is generated around the coil. This electric field then induces a magnetic field around the coil. This phenomenon is called Faraday’s Law of Induction. When the current flow through the inductor changes, either in magnitude or direction, the magnetic fields also change accordingly. This changing magnetic field then generates a counter electromotive force (emf). This emf is proportional to the rate of the change of current. This emf then opposes the applied voltage, which results in a voltage drop across the inductor.

Conclusion

The 4379-562JS fixed inductor is an ideal choice for high power applications in the automotive and power electronics industry. It is a shielded 29.9µH inductor with a current rating of up to 1.0A and a saturation current rating of up to 3.0A. It also has an excellent temperature resistance range, a lead-free design, a high surge current capability, and superior insulation due to its epoxy encapsulated terminal design. The inductor works on the principle of electromagnetic induction, where a changing current flow through the inductor induces a counter electromotive force that opposes the applied voltage. This results in a voltage drop across the inductor.
