Working Principle of SRR1280-470M Inductors

The SRR1280-470M inductor is a type of fixed inductor, which means that it has a fixed amount of inductance regardless of the applied voltage or current. The principle of operation of a fixed inductor is based on the behavior of a magnetic field when exposed to a changing current; when a current passes through an inductor, it generates a magnetic field that can store energy and can be used to oppose a change in current. As a result, when an AC voltage is applied to an inductor, the magnetic field opposes the varying current, causing the voltage to lag behind the current. This is known as inductive reactance, and can be mathematically represented by the equation: X_L = 2πfL, where f is the frequency and L is the inductance of the inductor.

The SRR1280-470M inductor is available in a wide range of inductance values from 0.47 µH to 470 mH. It is also available in various standard sizes from 0.125" x 0.1875" to 0.5" x 0.75". The inductor can handle a wide range of input voltages up to 25V AC, and has a maximum current handling capacity of 4.7 Amps. The inductor is constructed with high quality metal cores for maximum efficiency, and has an operating temperature range of -40°C to +125°C.
