Fixed inductors often play important roles in electrical circuits. They are widely used in circuits to filter signals, regulate frequencies, store energy, protect circuits from overvoltage and overcurrent, and much more. 103-680M fixed inductors are no exception. This article will discuss the application fields and working principles of 103-680M fixed inductors.

Application Fields

103-680M fixed inductors are commonly used in radio frequency (RF) applications such as mobile phones, 2G/3G/4G communication systems, Wi-Fi, Bluetooth, and other wireless communication technologies. They are also used in power electronic circuits such as switching power supplies, frequency converters, motor control systems, IT and medical equipment, automotive electronics, and entertainment devices.

Working Principle

Fixed inductors are basically inductors with a fixed inductance value. They are used to store energy in the form of a magnetic field. When an AC voltage is applied to the inductor, an alternating magnetic field is generated which is proportional to the applied voltage. This magnetic field is captured by the inductor’s inductance and stored in the form of energy. When the voltage is removed, the stored energy is released in the form of a current.

103-680M fixed inductors employ both ferrite and powdered iron cores. The ferrite core is able to store more energy than the powdered iron core while the powdered iron core can increase the inductor’s inductance value more quickly than the ferrite core. This combination of ferrite and powdered iron cores results in an inductor with high efficiency, low DC resistance, and low AC losses.

103-680M fixed inductors typically have a rated current of 0.15 to 10 Amps, an inductance range of 0.03 to 680 µH, and an operating temperature range of -40 to +105°C. The inductors also come in a variety of package sizes including SMD, THT, and MTD.

Conclusion

103-680M fixed inductors are widely used in RF and power electronic circuits due to their high efficiency, low DC resistance, and low AC losses. The inductors rely on both ferrite and powdered iron cores in order to achieve their desired performance and have a rated current of 0.15 to 10 Amps, an inductance range of 0.03 to 680 µH, and an operating temperature range of -40 to +105°C.
