Fixed inductors are electronic components used in power and signal circuits to introduce inductance. There are many different types of inductors available on the market depending on the application, such as air coils, ferrite cores, and planar chip inductors. A popular type of fixed inductor is the PL9128NL, a very common SMD type chip inductor used in many applications.

The PL9128NL is a low-profile SMD surface-mount inductor designed for use in various applications including power conditioning, voltage regulation, voltage conversion, and line regulation. It is designed to offer high performance in a compact package, and thus is becoming increasingly popular in power supply and frequency converter applications. The inductor is composed of a monolithically integrated ceramic component, which significantly reduces size and improves efficiency.

The PL9128NL chip inductor has a high current rating of 45 A, making it suitable for high-power applications. It has an inductance value range from 0.4 µH to 4.7 µH, and an operating temperature range of -40°C to +85°C. Furthermore, the recommended soldering temperature is 260°C for 10 seconds. The inductor is RoHS-compliant and is available in a variety of sizes.

The working principle behind the PL9128NL chip inductor is the same as for any other inductor. An AC current passing through the inductor creates an opposing magnetic field, as a result of Faraday’s Law of Induction. This opposing magnetic field induces an opposing EMF, creating a resisting effect and thus generating opposition to the change of current. This opposition to the change of current is known as inductance.

The PL9128NL chip inductor is ideal for applications which require a low-profile, high-performance inductor. Its wide range of inductance values makes it suitable for a variety of applications, and it is particularly well-suited for power conditioning, voltage conversion, and line regulation.
