Fixed Inductors

Inductors, also known as coils, are core components in electrical engineering. When an alternating current passes through the coil, it induces a magnetic field that generates a voltage in the same coil, thus restricting its own circuit current. A fixed inductor is a type of inductor whose inductance value remains constant over a wide range of frequency. SC75B-100 is one example of a fixed inductor.

SC75B-100 Application Field

The SC75B-100 fixed inductor is widely used in electrical equipment. It can be used for Voltage Regulator, DC to DC Converters, DC-AC Inverter, Anti-interference, Radio Frequency Circuits, Computer Peripheral Circuits, Output Inductors, Flyback Transformers, etc.

Working Principle

The SC75B-100 fixed inductor is built around an air-core inductor. This inductor has a ferromagnetic core made of MnZn, which is wrapped around by a coil of insulated wire. The inductor is polarized so that a magnetic field is generated when current flows through the coil, and this magnetic field produces a self-induced voltage in the coil. This voltage opposes the applied voltage, so that the current in the coil becomes limited. Thus, this inductor creates an impedance that restricts the current flow of the circuit. Apart from the air-core inductor type, there are two other types. One type is the choke inductor, which consists of an inductor wound around a core of ferrite or powdered iron. When the coil of this type is energized, an electromagnetic field is generated, creating an inductance. The advantage of this type of inductor is that more current can be drawn from it due to the high magnetic field. The other type is the transformer inductor, which is used mainly for DC to AC conversion or matching output impedance in electrical equipment. It is a combination of several layers of insulated wires wrapped around a ferrite core.

Benefits of SC75B-100 Fixed Inductors

The primary benefit of SC75B-100 fixed inductors is that they have a high inductance value, which means they can handle large currents. Furthermore, they have a wide operating temperature range, meaning they can work in high temperatures without compromising performance. Additionally, these devices can work at high frequencies due to their low parasitic capacitance and resistance, so they can be used for high-frequency applications. Furthermore, these inductors have a high resistance to moisture and humidity, and they are highly reliable, making them suitable for various applications.

Conclusion

The SC75B-100 fixed inductor is a highly reliable and versatile device that can be used in various electronic applications. It has a wide range of applications, from voltage regulators to flyback transformers, and it can handle large current levels. Furthermore, it is capable of operating at high frequencies due to its low parasitic capacitance and resistance, as well as its resistance to moisture and humidity. All in all, the SC75B-100 fixed inductor is an excellent choice for various electrical engineering projects.
