Introduction

The IHB3BV390K is a Fixed Inductors, designed for a variety of applications which require precise control of inductance and current characteristic. It is widely used in power, automotive and communications industries.

Application Field

The IHB3BV390K is mainly used in power systems such as power supplies and industrial motors, in automotive industry, such as fuel injectors, ignition systems, headlights, alternators, and in communications systems such as radio receivers and transmitters. It can also be used in various types of home appliances and consumer electronics.

Working Principle

The working principle of the IHB3BV390K is based on Faraday\'s law of induction. It has an internal circuit which contains a core composed of a ferromagnetic material and two coils—the primary and secondary. When the circuit is energized, an alternating current flows through the primary coil, inducing a magnetic field inside the core. This field induces an electromotive force (EMF) in the secondary coil, the magnitude of which depends on the turns ratio of the primary and secondary coils. The induced EMF of the secondary coil then opposes the initial EMF or voltage applied to the primary coil. This resistance to current change results in a surge of electric energy, and is also known as dynamic inductance.

Characteristics

The IHB3BV390K is characterised by high electrical efficiency, low power consumption, low electrical noise and high frequency response. It is also highly resistant to temperature variation, shock and vibration, and can operate between -55 and +125 degrees Celsius. It has a low profile induction design, making it ideal for high-density switch-mode power supplies and communications systems. The IHB3BV390K provides high linearity and low core power dissipation.

Conclusion

The IHB3BV390K fixed inductors are designed for a wide range of applications which require precise control of inductance and current characteristic. It is characterised by high electrical efficiency, low power consumption, low electrical noise and high frequency response, as well as high resistance to temperature variation, shock and vibration. The IHB3BV390K is ideal for high-density switch-mode power supplies and communications systems.
