Fixed Inductors

A fixed inductor, otherwise known as a fixed-value inductor, is a passive electrical component with a fixed inductance. Common fixed inductors are made out of wire and have a special core material that controls the inductance of the inductor. The inductance of the inductor is the primary parameter used in the selection of the inductor and is typically available in a range of inductances. One example of a fixed inductor is SC104-331, which is commonly used in the manufacture of electronic equipment and devices. It is a fixed-value inductor with a high rated current and a low DC resistance. SC104-331 is a high-quality, microwave-grade inductor designed for use in high-frequency applications.

Application Field

SC104-331 is suitable for a wide range of applications, including cellular phones, military communications, automotive electronics, communications infrastructure, medical electronics, consumer electronics, and more. This inductor is particularly useful in applications such as:

• High-frequency filter circuits
• To improve power supply rejection ratios, noise immunity, and so on
• RF amplifier circuits
• DC-DC converters
• Radar and communication systems
• High-frequency logic circuits

Working Principle

Fixed inductors work by inductance, which is the ability of a device to store energy in the form of a magnetic field. When an alternating current (AC) passes through the inductor, the magnetic flux generated by it winding opposes the changing current, creating a voltage drop that is proportional to the rate of change of the current. This voltage drop is known as the back electromotive force (EMF), which is directly proportional to the inductance of the inductor.In its basic form, a fixed inductor consists of two current-carrying coils: one is the coil of wire wound around a conductive core, and the other is a metal shield. The coil forms an inductive loop with its core material acting as a magnetic core. As a current flows through this loop, it produces a magnetic flux around the inductor, which is in turn opposed to the incoming current. The magnitude of the inductance of the inductor is determined by the core material, number of turns of the coil, and the shape of the coil. The inductance of the inductor is typically expressed in millihenries (µH). For SC104-331, the inductance range is from 300 to 500 µH.

Conclusion

SC104-331 is a fixed inductor, a type of passive electrical component with a fixed inductance. It is suitable for a wide range of applications in various industries such as cellular phones, automotive electronics, and consumer electronics. This inductor is ideal for high-frequency circuit designs, as it has a high rated current and a low DC resistance. The inductance of SC104-331 ranges from 300 to 500 µH, and it works by inductance, the ability of a device to store energy in a magnetic field.
