Fixed Inductors

Inductors are widely used in a variety of electrical applications, from power supplies to audio and video equipment. They are also used for filtering and coupling signals such as radio frequencies, and in radio frequency identification (RFID) tags. The 70F473AI-RC is a fixed inductor that is ideal for high-power applications.

Application Field

The 70F473AI-RC is suitable for a wide range of applications, including power sources, amplifiers, loudspeakers, RFID readers and transmitters, high-precision filters, and audio frequency filters. It can also be used in a wide variety of audio and video equipment such as surround sound systems and home theater systems.

General Characteristics

The 70F473AI-RC is constructed from high-grade materials for excellent performance. It features low core loss, low dc resistance, low temperature coefficient, and high inductance stability. It is available in a variety of sizes with a range of inductance values. The 70F473AI-RC also offers excellent acoustic performance, low distortion, and a low inductive resonance body.

Working Principle

The 70F473AI-RC works on the same principle as all inductors. It is an inductive component made up of a number of turns of a coil wound around a core material such as iron or ferrite. An AC signal is applied to the coil, which causes an alternating magnetic field to be generated. This magnetic field induces a counter EMF in the coil, which is proportional to the rate of change of current. In other words, the current will follow the shape of the applied signal.The 70F473AI-RC has the ability to filter out unwanted frequencies, allowing the desired signal to pass through. This is due to the fact that the higher frequencies induce a greater counter EMF, so they are more heavily suppressed than the lower frequencies. The 70F473AI-RC is also able to store energy, as the changing magnetic field in the core will induce a corresponding electric field which can be tapped off. This makes the 70F473AI-RC an ideal choice for power supplies, as it can generate extra voltage when required.

Conclusion

The 70F473AI-RC is a high-performance fixed inductor ideal for a wide range of applications. It has excellent performance characteristics and a low inductive resonance body. The 70F473AI-RC works on the same principle as all inductors, and its ability to filter out unwanted frequencies and store energy makes it an ideal choice for power supplies and audio and video systems.
