Introduction

PE-53661NLT is a fixed inductor. This component consists of a coil wound on a ferromagnetic core that supports and stabilizes the magnetic field generated by the current. By providing resistance to the flow of current, inductors store energy in the form of a magnetic field. Depending on the design, inductors can serve various functions such as voltage regulation, signal processing, and protection from electrical surge.

Application

PE-53661NLT is primarily used in power supplies, battery chargers, transformers, and voltage doubling circuits. It is a common component used in circuit boards that require a stable current that is relatively constant over a wide range of input conditions. In some cases, the PE-53661NLT can also be used for signal filtering and sensing applications.

Working Principle

The operation of an inductor is based on Faraday’s law of induction, which states that a changing magnetic field produces an EMF in a circuit. As current passes through the winding in an inductor, a magnetic field is created. This magnetic field, in turn, is attracted to the core of the inductor, resisting the flow of current and producing what is known as a back EMF (electromotive force). This back EMF then opposes the initial EMF generated by the battery or power source, creating a “drooping” effect on the current.

Design of PE-53661NLT

The PE-53661NLT is designed to provide a highly consistent and stable current, even with wide input variation. It is a surface mount component, measuring in at 8mm x 10.7mm (0.3in x 0.42in). The inductance value of the PE-53661NLT is 6.5uH (micro henries), with a current rating of 3.2A (amps) and a DC resistance of 0.068Ω (ohms).The component also includes a molded terminal block in order to ensure optimal circuitry performance. The molded terminal block helps to reduce the amount of inductance variation due to manufacturing irregularities found in terminal connections. Additionally, the molded terminal block improves the thermal dissipation as it increases the heat transfer rate.

Conclusion

In conclusion, the PE-53661NLT is a fixed inductor designed for use in a variety of applications such as power supplies, battery chargers, transformers, voltage doubling circuits, and signal filtering and sensing applications. This component is designed to provide a highly consistent and stable current, even with wide input variation, and includes a molded terminal block for improved thermal dissipation and inductance variation reduction.
