Fixed inductors are widely used in electronic equipment for various applications and are designed to provide various levels of electrical impedance, magnetic flux, or power transfer characteristics. The 103-123GS series of fixed inductors is a practical solution for many applications such as power amplifiers, audio power supplies, and DC to DC converters.

Physical Characteristics

The 103-123GS is a pancake-shaped, multilayer inductor having a diameter of approximately 5mm and a thickness of 1.5mm. The core is made of ferrite and the winding consists of an enameled copper wire. The inductance range consists of 1 - 3 uH and the maximum DC current rating is 7 Amps.

Operation

The 103-123GS is designed to provide a steady current flow, while minimizing the voltage drop across the component. It works according to the principle of electromagnetic induction, wherein the magnetic field generated by the current passes through the core of the inductor and induces a current in the winding. This induces a voltage across the winding and opposes the applied voltage, thus providing a limited impedance to the flow of current.

Applications

The 103-123GS inductors are used in a wide variety of electronic applications. These include power amplifiers, audio power supplies, DC to DC converters, switch mode power supplies (SMPS), DC to AC converters, electric motor drives, and various other power related circuits.

In power amplifiers, the 103-123GS inductors are used to provide filtering for the DC current. This reduces the amount of RF interference generated by the amplifier. In DC to DC converters, these inductors are used to boost the efficiency of the system by reducing the amount of voltage drop across the inductor in the presence of a large load. They also help to reduce electromagnetic interference (EMI) generated by the system due to their low inductance.

In audio power supplies, the 103-123GS series of inductors are used to provide a steady current flow to the audio circuits. This helps to reduce distortion and maintains a consistent signal level.

In electric motor drives, the 103-123GS series of inductors is used to provide a steady voltage and current to the motor. This helps to reduce the amount of power dissipation in the motor and thus increase its efficiency.

In switch mode power supplies (SMPS), the 103-123GS inductors are used to reduce the current ripple generated by the rectifiers and thus improve the efficiency of the system. They are also used in power systems to reduce the inductive losses due to the presence of large loads.

Conclusion

The 103-123GS series of fixed inductors is an ideal solution for a wide variety of electronic applications, especially in power systems. They are designed to provide a steady current flow, reduce voltage drop, and minimize EMI. They are also used to boost the efficiency of DC to DC converters and reduce losses in electric motor drives. Additionally, the 103-123GS series of inductors can help to reduce noise and distortion in audio power stages.
