Fixed inductors are an important family of electronic components for realizing DC/AC circuit conversion. The PL8909NL is a device that falls into this family and it is an ideal component for DC/AC conversion applications. This article will discuss the application field and working principle of the PL8909NL.

The PL8909NL is an inductor specifically designed for use in high-frequency switching power supplies. It has a DC bias current of 2 A and an operating frequency range of 200 kHz to 2.3 MHz. Its low profile design helps reduce power conversion losses. The device also has a rated inductance of 22 uH and a tolerance of 5%.

The PL8909NL is suitable for use in boosting and step-down switching power supplies, flyback DC/DC converters, and half-bridge DC/DC converters. It can also be used as a component in a transformer in order to realize galvanic isolation. In addition, the device is well-suited for use in DC-DC converters of various power levels.

The working principle of the PL8909NL is based on Faraday’s law of electromagnetic induction. This law states that when a conductor is in a changing magnetic field, an electric current will be induced in the conductor. This relationship is true for both inductors and transformers. The magnetic field is created by a current flowing through the coil of wire that forms the device.

When an AC voltage is applied to the coil, the current produces a varying magnetic flux, which in turn produces an induced voltage in the coil. This induced voltage opposes the applied voltage, causing the inductor to store energy. The amount of energy that is stored is proportional to the amount of inductance in the device. Thus, the higher the inductance, the greater the stored energy and the greater the voltage drop across the inductor. As the current through the coil increases, the magnetic field increases and so does the stored energy.

The PL8909NL can also be used to provide a high-frequency DC current filter. This is due to the fact that as the frequency of the input signal increases, the inductor’s reactance increases and the current through the inductor decreases. This allows an AC signal to pass through the inductor while blocking the DC signal.

The PL8909NL is an ideal choice for applications requiring high-frequency switching. It has a low height profile which makes it suitable for use in a variety of applications. It has a rated inductance of 22 uH and a tolerance of 5%. Its DC bias current is 2 A and its frequency range is 200 kHz to 2.3 MHz. The device is well-suited for use in boosting and step-down switching power supplies, flyback DC/DC converters, half-bridge DC/DC converters, and as a component in a transformer for galvanic isolation. The working principle of the device is based on Faraday’s law of electromagnetic induction.
