Ferrite Chip Wirewound Inductors Characteristics and Applications

Ferrite chip wirewound inductor is a common electronic component, which is made of ferrite material with anti-interference, spike and ringing suppression characteristics, and is widely used in RF and microwave circuits, power supply systems, and small-signal multi-stage amplification circuits. Compared with common wirewound Inductors, ferrite chip wirewound inductors have the following characteristics and applications:

1. Anti-interference characteristics: Ferrite chip wirewound inductors have high magnetic permeability, osmosis of zinc, magnesium, nickel and other metal materials burned together, with a low value of the inductive impedance of the anti-interference core at low frequencies, high-frequency impedance increase characteristics. Therefore, the ferrite chip wirewound inductor shows excellent performance in suppressing high frequency interference, and its performance is also quite excellent in suppressing low frequency interference.

2. Spike and ringing suppression: Ferrite chip wirewound inductors can effectively suppress spikes and ringing in high-speed signal transmission, thus improving the stability and reliability of signal transmission.

3. Application: Ferrite chip wirewound inductors are used in RF and microwave circuits to decouple the power supply system and prevent bad coupling between stages, especially in small signal multi-stage amplification circuits compared with ordinary wirewound inductors, ferrite inductors will not produce new sources of interference. In addition, ferrite chip wirewound inductors are also widely used in computer monitors, keyboards, mice on the connection line, as well as other electronic devices in the power supply circuit.

4. Impact of package size on electrical performance: The package size of ferrite chip wirewound inductors has an impact on the electrical performance, but there are other factors such as the production materials, processes, formulations, and winding methods will also affect the electrical performance of the inductor. Therefore, it is necessary to match the actual application scenarios and requirements when selecting inductors.

Overall, ferrite chip wirewound inductors are widely used in RF and microwave circuits, power supply systems, and small-signal multi-stage amplification circuits because of their anti-interference, spike suppression, and ringing characteristics. When selecting inductors, it is necessary to match them with the actual application scenarios and requirements to ensure the performance and reliability of ferrite chip wirewound inductors.
