Fixed Inductors

Inductors are electronic components that can transmit electrical energy in the form of an electric current. They can be fixed or variable, meaning that the current may be adjustable, either by simple manual adjustment or automatically, via electronic control. The 8532-39H is a fixed inductor, which can be defined as completed units that provide constant and predictable inductance, designed not to be adjusted.

Application fields and working principle

The 8532-39H fixed inductor is mainly used in RFID, high frequency control circuits, over-current protection circuits and high-frequency circuit protection. Its working principle involves the phenomenon of self-induction. When a current passes through the inductor, an electromagnetic induction field is generated around the winding, causing the inductance to increase, and the impedance of the inductor is also changed. This change is known as the self-inductance effect.

The value of the inductor\'s self-inductance is inversely proportional to its total flux. That is to say, when the input alternating current frequency increases, the inductor\'s self-inductance decreases and the current rises. In order to reduce the resonance phenomenon caused by the self-inductance effect, a capacitor or resistance can be connected in parallel or in series with the inductor.

The internal structure of fixed inductors can be divided into two types: air core inductors and ferrite core inductors. An air core inductor is composed of a copper wire wound around an inert core, while the ferrite core inductor includes a ferrite material made of magnetic particles surrounded by the copper wire. The advantage of the air core inductor is its low boundary, while the ferrite core inductor is superior in terms of inductance and capacitance. Depending on its intended purpose, different specification and working range of 8532-39H fixed inductors are usually available.

The 8532-39H fixed inductor features a tight tolerance level allowing precise control over the inductance level. It has a maximum operating temperature of 125°C, with a rated nominal DC current of up to 1.5A, and a maximum rated peak temperature of up to 2.2A. Designed in a compact size, this inductor also comes with a low DCR value as low as 10 mOhm, providing efficient performance. The 8532-39H fixed inductor is usually designed with silver-read solder plated terminals and an insulation sleeving for superior strength and electrical insulation.

As a fixed inductor, the 8532-39H has the advantages of higher frequency response, low power consumption, low noise, and high frequency stability. It is also lightweight and cost effective. It has a wide range of applications, such as RFID, high frequency control circuits, over-current protection circuits, high-frequency circuit protection, and many more.

In summary, the 8532-39H fixed inductor is a small but powerful device and offers superior electrical performance. Its low power requirements and tight tolerance level enable it to be specifically designed to work in a wide range of applications, ensuring superior performance with minimal energy consumption.
