Introduction

Fixed inductors, or inductors with fixed inductance, are electric components that store energy in an inductive coil created by a current-carrying conductor and provide the current with a resistive load. PA4309.333NLT is an example of such a vital component. It is specially designed for applications in power supply regulation and communications. This article will focus on PA4309.333NLT\'s application field and working principle.

Application Field

PA4309.333NLT is primarily used in products that require low-impedance performance and ultra-high inductance. It is especially well-suited for use in switchers, voltage regulators and on-board power-line noise suppression, as well as lightweight and space-saving applications. It features a non-shielded construction, which is relatively small and space-saving. The cylindrical shape also makes it easy to install and its small size makes it an ideal component for applications in tight spaces. It is void free, meaning there are no bubbles or other defects in the coils, which helps to ensure long-term performance. Moreover, PA4309.333NLT is RoHS compliant and has a wide operating temperature range from -30 to +85 °C. PA4309.333NLT has excellent electrical performance and protects electrical circuits against overvoltage transients. It is also a cost-effective solution for DC/DC converters due to its remarkable power handling capabilities. In addition, it has excellent thermal resistance, which helps reduce energy consumption and increases efficiency.

Working Principle

The function of an inductor is based on Faraday\'s laws of induction. An inductor consists of a conductive material, which when a current passes through it, induces a magnetic field. This magnetic field then stores energy within the magnetic field lines.Once the current passes through the inductor, the quantity of the current influences the magnetic field and the energy stored within it. The size and shape of the magnetic field depend on the current passing through it and is called inductance. PA4309.333NLT uses a flat spiral coil and its core consists of a ferrite material. This component combines the high inductances of a flat spiral coil and the low core loss and high permeability of ferrites. The input current exerts an external force on the coil, creating a magnetic field. This magnetic field then induces a voltage in the coil. This voltage is the opposite of the original voltage, and this opposes the flow of current. This opposition is called inductive reactance and is expressed in ohms.

Conclusion

PA4309.333NLT is an example of a vital fixed inductor, designed for power regulation and communication applications. It is size-efficient, cost effective, and offers excellent electrical performance, high power handling capabilities, and remarkable thermal performance. Its working principle is based on Faraday\'s laws of induction and is based on the size and shape of a magnetic field that is created when an input current passes through it. Overall, it is a versatile component and a great choice for many power supply applications.
