This versatile component can boost the performance of EMI filters, power amplifiers, and other power delivery systems. The HKQ04021N2S-T is available in an SMD (Surface Mount Device) package, allowing for easy integration on circuit boards.

Working Principle

A fixed inductor, such as the HKQ04021N2S-T, works on the principle of Faradays law of induction. This law states that, when a current passes through a coil of wire, a magnetic field will be created around the coil. As the current passes through the coil, the magnetic field builds up and stores energy. This energy is essentially stored in the form of an electromagnetic force. The force can then be used to induce current in another coil.

The HKQ04021N2S-T has a number of features that make it a good choice for various applications. It can handle frequencies ranging from 100MHz up to 5GHz, allowing it to be used in many different applications. It is also able to handle up to 5 Watts in power, making it suitable for a wide range of use cases. Additionally, its small size and SMD package means that it is very easy to install and integrate into existing systems.

Conclusion

The HKQ04021N2S-T is a fixed inductor that has application fields and a working principle that make it suitable for a wide range of uses. It has power handling capabilities of up to 5 Watts, and the SMD package allows for easy integration. Furthermore, it can handle frequencies ranging from 100MHz up to 5GHz. Therefore, it can be used in high frequency switching power supplies, dc/dc converters, ripple filters, RF applications, and even energy storage systems. It is a versatile component that can be used in many different applications.
