Fixed Inductors are commonly used to store energy inside an electric circuit. They are often found in the form of coils and are composed of a single or multiple metallic conductive wires wound around a magnetic or non-magnetic core. The inductance of a particular inductor is determined by the number of turns in the coil, the core material, the core diameter and length, as well as the distance between the turns. The fixed inductor PE-1008CM911JTT is specially designed for high-frequency power supplies, and its applications as well as working principles are discussed in the following sections.

Applications

The PE-1008CM911JTT Fixed Inductor is designed for high-frequency power supplies. Its high-saturation core and superior Q-factor make it an ideal choice for applications such as multi-voltage switchers, switching power supplies and DC-DC converters. It also offers good noise immunity and an effective EMI filter in switching power supplies. In addition, it can be used as a current-balancing choke in battery chargers, inverters, and LED lighting systems.

Principle of Operation

The PE-1008CM911JTT Fixed Inductor works on the principle of electromagnetic induction. When an alternating current passes through the magnetic core of the inductor, it generates an alternating magnetic field which in turn induces an opposing voltage in the coil windings. The induced voltage opposes the original applied voltage, creating a self-induced back-EMF. This back-EMF induced in the coil is proportional to the rate of change of the current flowing through the inductor. Because of the energy stored in the coil, the inductor will have a certain amount of resistance to changes in current, thus causing the current in the circuit to “lag” behind the applied voltage. The amount of inductance generated by the coil is determined by the number of turns, the core material, the core diameter and length, as well as the distance between the turns.

Fixed Inductors are especially useful in pulse-width modulated (PWM) circuits, where they can be used to filter high-frequency components from a PWM signal. The inductor’s self-induced back-EMF acts as a low-pass filter, allowing only the lower frequency components of the signal to pass through. The PE-1008CM911JTT Fixed Inductor is also useful for creating low-voltage power supplies, and for applications such as signal delay circuits.

In summary, the PE-1008CM911JTT Fixed Inductor is an ideal choice for high-frequency power supplies, providing good noise immunity, effective EMI filtering, and excellent current-balancing capabilities. Its use in pulse-width modulated circuits as a low-pass filter, and in signal delay circuits, allows it to be used in a wide range of applications.
