Fixed inductors are electrical components that are designed to provide a constant level of inductance, regardless of frequency. 4302R-223K are a type of fixed inductor, which are specifically designed for use with SMD printed circuit boards. This article will aim to provide an overview of their application field and working principle.

4302R-223K Application Field

4302R-223K are a type of 4302R inductor series, which are developed and manufactured by Tachyon Technologies Corporation. This series was specifically designed for applications in switched-mode power supplies, as well as lamp and motor drives. The 4302R-223K SMD models feature a rectangular shape, with dimensions of 26 mm by 14 mm by 7 mm. They also offer an inductance range from 1 to 4.7 uH.

The 4302R-223K series is generally used in many high-power switch options. They offer improved EMI performance, with a higher current-handling capacity than traditional inductors. 4302R-223K can handle currents of up to 12 A, at an operating temperature ranging from -55 to +125 °C. They also feature a low resistance of 0.4-0.5 mΩ, depending on the specific model.

Working Principle

The 4302R-223K series operate on the principle of inductance, which is a property of electrical circuits. The 4302R-223K features two metal contacts and a coil of conductor. When a signal passes through the contacts, the current generates a magnetic field, which produces an effect called "back-EMF". This back-EMF induces a voltage in the coil, which creates a circuit with an inductance of 4.7 uH. As the frequency of the signal increases, the inductance of the 4302R-223K will remain constant, regardless of frequency.

The 4302R-223K series of inductors are also designed with a ferrite core, which helps to reduce the amount of energy lost from the inductor. The ferrite also helps to minimize the amount of electromagnetic interference (EMI) that is emitted from the inductor. This allows the 4302R-223K inductors to operate more efficiently, while also reducing interference with other electronic components in the system.

Conclusion

The 4302R-223K series of fixed inductors are designed for use in high-power switch applications, such as switching power supplies and motor drives. They feature a rectangular shape and an inductance of 1 to 4.7 uH. The 4302R-223K inductors are also designed with a ferrite core to reduce the amount of energy loss, while also reducing the amount of EMI emitted from the inductor. This makes the 4302R-223K an ideal choice for SMD printed circuit boards in a wide variety of applications.
