Fixed inductors are electronic components that consist of an insulated wire or coil wrapped around an iron core or ferrite slab. The coils act as inductors, meaning they store energy in the form of an electromagnetic field. Fixed inductors are used in a variety of circuits, but their primary function is to store energy and help oscillate, amplify, filter, or regulate signals in applications such as amplifiers, digital-to-analog converters, radio receivers, and even switching power supplies. The Fixed inductors are generally categorized based on their specific operation, form factor, and function.

The PL8503NL is a state-of-the-art fixed inductor that features a high self-resonance frequency for maximum SMT mounting density. It also features a small surface mount inductor with higher current capacity than conventional surface mount inductors. The PL8503NL is perfect for power supplies, filter circuits, and even for common mode choke applications as it features a wide operating temperature range from -40°C to +120°C.

The PL8503NL is an integrated passive surface mount device (IPD) designed for automotive applications. It operates on a variety of frequencies and features an impressive high quality factor (Q) of 33.3 and an inductance value of 1.2uH. The low profile of the PL8503NL allows for efficient heat dissipation which enables the high current and high temperature functionality.

The working principle of fixed inductors involves storing energy in the form of an electromagnetic field. An AC current is applied to the coil, creating a magnetic flux and generating a magnetic field. This magnetic field will be weaker in strength compared to that of a permanent magnet but its effect remains the same. This energy stored in the magnetic field is then released back into the circuit, either as a direct current or as a current of alternating direction.

The PL8503NL uses a self-shielding metal core for increased stability and reduced leakage inductance over maximum frequency range. The ferrite core also improves the operating temperature range of the device and increases self-resonance frequency. Additionally, the device uses multilayer construction to minimize the distributed capacitance and inductance, allowing for improved high frequency performance.

Applications of the PL8503NL can be found in a variety of applications including audio amplifiers, DC-DC converters, power supplies, common mode chokes, and LCD displays. As an extremely low profile surface mount inductor, the PL8503NL is also popular for use in highly competitive radio frequency (RF) applications, offering both high operating temperature range and high self-resonant frequency.

In conclusion, the PL8503NL is a state-of-the-art fixed inductor with a wide variety of operating frequencies and features a high quality factor (Q). It has excellent performance characteristics at both low and high frequencies, making it well suited for RF applications. It has a low profile for efficient heat dissipation and high current and temperature capabilities, allowing for use in a variety of applications.
