Datasheet

## **RF Inductor** 

## **BWCS 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. Can maintain excellent thermal stability at different temperatures 

## **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
