Fixed Inductors

Inductors are passive electronic components used in electrical circuit designs to store energy in the form of a magnetic field. An inductor is basically a coil of wire wrapped around a core material. Fixed inductors are inductors with an unchanging inductance, meaning that their inductance value does not change under fixed wiring conditions. The HCT-374 is a type of fixed inductor ideal for power supplies and audio applications.

Application Field

The HCT-374 fixed inductor is a single layer power inductor with excellent properties such as low profile, high saturation current and low-resistance. It is widely used for DC-DC converters, SMPS, and audio applications. It has an inductance ranging from 43nH to 470nH, a rated current of up to 11.00 Amps, and an operating temperature of -40°C to +125°C.

In terms of DC-DC converter applications, the HCT-374 is suitable for use in switching power supplies, battery chargers, DCDC converters, and communications applications. It is also used for automotive applications, such as powertrain systems, lighting systems, and engine control systems. The HCT-374 is also suitable for audio applications such as preamplifiers, amplifiers, and outboard audio devices.

Working Principle

An inductor works by generating a magnetic field around the conductor. This magnetic field stores energy in the form of a magnetic field. When current is applied to an inductor, it generates a magnetic field, which induces current to flow in the opposite direction. This is known as inductive coupling or mutual inductance.

A fixed inductor, such as the HCT-374, has a set number of winding turns and a constant current proximity. As a result, the inductance of the inductor remains unchanged. In the case of the HCT-374, the windings are formed into a single-layer air core inductor. This helps to reduce eddy currents and minimizes size and weight.

The air core feature of the HCT-374 allows it to have low magnetic distortion, and also a higher self-resonance frequency. This allows it to be used in audio applications such as preamplifiers, amplifiers, and outboard audio devices, where quality audio is of paramount importance.

In short, the HCT-374 fixed inductor is a cost-effective and reliable component for power supplies, automotive applications, audio applications, and other circuit designs requiring a fixed inductance value.
