Fixed inductors are key components in electronic circuits. One of the most commonly used types is the PL8910NLT, which is characterized by its operating temperature range, self-resonance frequency, high current capability, and low EMI noise.

The PL8910NLT is an axial-lead, low self-inductance, ferrite core fixed inductor by Pulse Electronics. It has a current rating of up to 10A and operating temperature range from -40 to 125°C. Its self-resonance frequency is usually between 120 kHz and 200 kHz, depending on the package size and inductor value.

The most common application of the PL8910NLT is in switched-mode power supplies (SMPS) for personal computers, TV displays, and other electronic components. The inductor provides a low-impedance path for current, allowing for more efficient power supply designs. The low EMI noise generated by this inductor is ideal for applications where noise generated by the inductor is a concern.

The working principle of the PL8910NLT is based on the law of induction. This law states that a changing magnetic field induces an electric current in a nearby conductor. The PL8910NLT uses a ferrite core, which has a high permeability, to create a strong magnetic field. When alternating current (AC) passes through the coil wound around the core, a changing magnetic field is generated. This changing field induces a current in the surrounding conductor.

The strength of this current depends on the number of turns of the coil, the frequency of the AC power, and the size of the core. With a larger core, more current is induced in the surrounding conductor and a stronger magnetic field is created. This increase in current also results in a higher inductance, which is measured in Henries.

The PL8910NLT is designed to be very small and lightweight while still providing a high current rating and low EMI noise. Its small size and weight makes it ideal for applications where size and weight are factors. It is also very efficient, making it cost effective while still providing excellent performance.

In summary, the PL8910NLT is a fixed inductor with a wide operating temperature range, high current rating, low EMI noise, and small package size. It is designed for use in switched-mode power supplies and other applications where efficiency and size are important. Its working principle is based on the law of induction and involves the use of a ferrite core and a coil to induce current in a conductor.
