Fixed inductors are widely used in a variety of electronic systems for a variety of purposes. B78148S1472J000 is a type of fixed inductor and these devices are designed to meet the need for an inductor that provides electrical and electronic parts with an inductance that does not significantly vary over its lifetime. In fixed inductor, the inductance provided by the device is typically much larger than that obtained from other components like capacitors or resistors.

B78148S1472J000 application fields include high-frequency circuits such as RF communication systems, RF filters, and high-frequency switching circuits. The working principle of B78148S1472J000 is based on electromagnetic induction. Electromagnetic induction is a process in which electric current carrying coils of wire create a magnetic field which in turn induces electric current in neighboring coils. This phenomenon has been utilized in the development of inductors, wherein the two coils of wire are connected in series with a core material placed in between. When an AC voltage is applied to the coils, a magnetic field is created in the air gap between the two coils, and the current flowing through the series connection causes the magnetic field to be concentrated in the core. This induces a voltage in the other coil, which is proportional to the change in flow of the current in the first coil. The core material used will dictate the amount of inductance obtained from the device.

B78148S1472J000 is based upon the same principle of electromagnetic induction as used for other inductors, but it has specific characteristics which set it apart such as its size, tolerances and temperature characteristics. Specifically, B78148S1472J000 has a small package size, tight tolerances and wide temperature range (-55°C to 125°C); making it suitable for use within a variety of demanding applications. Furthermore, B78148S1472J000 has a high self-resonance frequency, low DC resistance, and high inductance. As such, B78148S1472J000 is suitable for use as a DC-AC inverter, buffer and demagnetization coils, as well as for a variety of noise suppression and EMI reduction applications.

To conclude, B78148S1472J000 is a fixed inductor based on the principle of electromagnetic induction, which enables these devices to provide high inductance values in a small package size for a variety of applications. The device offers an extremely wide temperature range (-55°C to 125°C) as well as high self-resonance frequency, low DC resistance, and high inductance, allowing it to be used for DC-AC inverters, buffer and demagnetization coils, noise suppression or EMI reduction applications.
