The PL9130NL is a fixed inductor that can be used as either an RF choke or an RF filter in various applications. It is available in both a standard (10mm x 10mm x 4.3mm) and a custom size (18mm x 10mm x 4.3mm). The inductor has a minimum operating temperature of -40ºC and a maximum operating temperature of 105ºC.

The PL9130NL is used in a variety of RF applications, including DC-DC power converters, buck converters, linear regulators, boost converters, and single-phase inverters. It is also used in RFID tags, wireless charging circuits, and in high frequency applications such as VHF and UHF. The inductor is also used in WiFi, Bluetooth, and IR (Infrared) device front ends, providing the necessary common mode filtering or chokes to prevent external interference or to meet FCC radiated emission or harmonics standards..

The working principle of the PL9130NL is based on the concept of magnetic inductance. When an alternating current (AC) flows through the windings of the inductor, it creates a magnetic field. This magnetic field induces a magnetic flux which in turn causes a voltage to appear across the winding, with a value that is proportional to the rate of change of current through the inductor. This voltage is referred to as an induced electromotive force, or EMF.

The amount of induced EMF is determined by the number of turns on the inductor core, as well as the rate at which the current through the inductor changes. The induced EMF acts as a resistance to the flow of current, helping to limit the current draw of the device. This resistance is known as the inductive reactance. The greater the inductive reactance, the more current is restricted from flowing through the inductor.

The PL9130NL has a relatively low inductive reactance, which makes it suitable for high frequency applications. The inductor is also able to tolerate high ripple currents, making it ideal for use in switching power supplies.

The PL9130NL has a maximum inductance of 4.3nH, and a maximum DC current rating of up to 4A. The low-profile package of the inductor makes it ideal for use in portable devices, where size and weight are limiting factors. The inductor is also RoHS compliant.

In summary, the PL9130NL is a fixed inductor that is typically used to provide filtering or chokes in high frequency applications, and to limit the current draw of a device. The inductor is capable of handling high ripple currents, and its low-profile package makes it suitable for use in portable devices.
