## **RF Inductor** 

## **BWLS Series** 

## **Overview** 

Wire-wound RF inductors are electronic components designed to store energy in a magnetic field when electrical current passes through them. They are constructed by winding a conductive wire (usually copper or gold-plated) around a core material such as air, ceramic, or ferrite. 

This configuration allows them to provide high inductance values with minimal power loss, especially at high frequencies. 

## **Benefits** 

1. High Q-Factor (Quality Factor) 

2. Ceramic body and wire wound construction provide high SRFs 

3. Low DC resistance design 

4. High Current Handling 

5. Low inductance value 

## **Applications** 

1. Industrial and Medical Equipmen: RFID systems and medical imaging equipment. 

2. Data Centers 

3. Networking 

4. Base Station 

5. Consumer Electronics 

6. Security system
