Fixed inductors, such as the NL453232T-101J-PF, are an essential passive electronic component commonly found in many applications. They are used to create an electrical circuit with a specific inductance, which has different properties to a simple resistor. This article will explain the application field and working principle of fixed inductors.

Inductors are composed of a coil of wire, and generally come in two types – variable and fixed – with the NL453232T-101J-PF being a fixed inductor. Fixed inductors are usually used to filter out unwanted signals, provide energy storage, provide impedance matching between components and reduce electromagnetic interference in an electronic circuit.

Fixed inductors are typically connected to an external power source between its two terminals and a DC current flows through the coil. The magnitude of the current fluctuates in unison with the magnitude of the source voltage. As the current passes through the coil, its magnetic flux varies and creates an electromotive force in the opposite direction of the applied voltage.

As the magnetic flux builds up around the inductor, a counter-electromotive force called inductance is produced. Inductance is the inverse of resistance which causes the current to decay and be delayed within the coil. The inductance of an inductor is expressed in henrys, symbolised by the letter ‘H’.

The amount of current passing through the coil is controlled by the voltage on the terminals. The greater the voltage, the greater the current. This current does not flow in a steady state. Changes are constantly happening in the current, so that when the voltage is increased, the current is increased, and when the voltage is decreased, the current is decreased.

The NL453232T-101J-PF is a high-field inductor with a low resistance at high frequency, such as 20 kHz. It is ideal for noise suppression, counter measures, noise and power lines, EMC filters, and small signal circuits, as it has very low external magnetic fields and a wide operating temperature range.

The NL453232T-101J-PF is derived from a single steel tape, wire-wound type and is usually employed in applications where a large air-gap is required between the core and collector coils. It provides excellent low-frequency impedance stability and excellent leakage inductance to ensure maximum possible efficiency in power supplies and switching converters. It is also able to tolerate high frequency current.

Understanding how fixed inductors work is essential in order to identify their applications and to correctly use them in electronics. The NL453232T-101J-PF is an example of a fixed inductor, which is used in various applications such as noise suppression, counter measures, and noise and power lines. It is designed for low-resistance and high-frequency operation, offering excellent impedance stability and leakage inductance.
