Fixed Inductors

An inductor is a type of passive electronic component that is used to store electrical energy in the form of a magnetic field. They are widely used in electronic circuits to filter signals, reduce interference, and provide impedance matching. One of the most common types of inductors is the fixed inductor, which consists of a coil of wire that has a steady inductance value. The NL453232T-391J-PF is an example of a fixed inductor. This article provides an overview of the application field and working principle of the NL453232T-391J-PF fixed inductor.

Application Field

The NL453232T-391J-PF is a 4mm x 5mm surface-mount fixed inductor ideal for use in a wide range of applications. It is designed for use in power supplies, dc-dc converters, antennas, and other applications where high inductance and low profile components are necessary. The NL453232T-391J-PF can be used in high temperature environments, and its low profile allows it to fit into tight spaces. Additionally, it is RoHS compliant, making it suitable for use in environmentally sensitive applications.

Working Principle

A fixed inductor works by creating a magnetic field when a current passes through it. This magnetic field can store electrical energy in the form of a voltage. The voltage created is proportional to the magnitude of the current, the number of turns in the coil, and the ratio of the coil’s cross-sectional area to its length. By controlling the current and the number of turns of the coil, the inductance value of the fixed inductor can be adjusted. The NL453232T-391J-PF inductor has an inductance value of 3.9mH.

The NL453232T-391J-PF also has a high saturation current rating of 7.5A. This means that it can handle high current applications without losing its inductance value, allowing it to be used in high power applications. Additionally, its low DCR rating of 0.072 Ohms means that it very efficient and does not dissipate much heat.

Conclusion

The NL453232T-391J-PF is a 4mm x 5mm surface-mount fixed inductor that is ideal for use in power supplies, dc-dc converters, antennas, and other applications where high inductance and low profile components are necessary. It has an inductance value of 3.9mH and a high saturation current rating of 7.5A. Its low DCR rating ensures that it is very efficient and does not dissipate much heat. The NL453232T-391J-PF is RoHS compliant, making it suitable for use in environmentally sensitive applications.
