Fixed inductors are devices that provide resistance or impedance in circuits that, depending on the design, are not affected by temperature variations, changes in frequency of the signal they carry, or other environmental parameters, including shock and vibration. In many applications, fixed inductors are used to form LC filter networks that improve the signal-to-noise ratio and are used to filter out unwanted frequencies from the desired signal arriving at the output of the inductor.

The BRC2518T330M is a fixed-style inductor from ROHM SIEMENS. It features a size of 2518, a rated inductance of 330mH plus a minimum inductance of 294mH. The working frequency of the BRC2518T330M ranges from 100kHz to 1MHz, and the working DC current is 0.33Amps. Plus, its peak current rating is 3A and the DC resistance rating is 0.76ohms. The BRC2518T330M also has a high-frequency current rating of 0.12Amps, and an inductance tolerance of ± 30%.The BRC2518T330M is used in many applications including DC-DC converters, supercapacitors, inverters, laptops, multi-function printers, and other consumer electronic accessories. Its compact size and reliability make it suitable for desktop and mobile applications.The working principle of the BRC2518T330M is based on Faraday\'s Law. According to this law, an electrical current is induced in a circuit by a change in a magnetic field. An inductor coil is composed of a magnetic core material, and a winding of metal wire. When a current passes through the coil, a magnetic field is created that acts on the coil, inducing a voltage. The magnitude of the induced voltage depends on the rate of change of the current through the inductor. The total voltage across the inductor is the sum of the induced and the applied voltages.The further use of the BRC2518T330M is to reduce voltage spikes and provide additional insulation when switching power. In addition, its high peak current rating and low heating result in improved performance and longevity. It is also great for creating LC filter networks to filter out any signals outside the intended range of frequencies.In summary, the BRC2518T330M is a small fixed-style inductor suitable for use in mobile and desktop applications, featuring a size of 2518, a rated inductance of 330mH plus a minimum inductance of 294mH. Its working frequency range is from 100kHz to 1MHz, and the working DC current is 0.33Amps. Its peak current rating is 3A and the DC resistance rating is 0.76ohms. Its high-frequency current rating is 0.12Amps, and the inductance tolerance is ± 30%. It is used in many applications to reduce voltage spikes and provide additional insulation when switching power, as well as improve signal-to-noise ratio and filter out any signals outside the intended range of frequencies.
