Ferrite beads and chips in electronic circuits act as an EMI filter to reduce interference and unwanted signals. Among them, BK1608HS220-TV is a chip-type EMI filter which adopts capacitors and miniaturized inductor in a single chip. It primarily focuses on the application field and working principle of this typical EMI filter.

BK1608HS220-TV EMI filter is widely applied in various consumer electronics such as digital cameras, mobile phones, tablets, audio and video players. It features small rate of losses, low ESR, wide operating temperature range and excellent reliability. This type of filter could reduce undesirable frequencies signals and provide surge protection in such areas as automotive, communications, computer and wireless communications.

The working principle of BK1608HS220-TV is based on the electromagnetic field. The chip basically contains a capacitor, and an inductor. The capacitor serves to separate current frequency and divert components with high frequency, while the inductor most commonly reduces the peak of capacitor current. Thus, both of them together could reduce the peak voltage and clamp the EMF, protection the device from damage.

The capacitors and inductor also work collaboratively to limit power signal transmission from source to device, which ensure uninterrupted performance of the electronic device it protects. Moreover, the ferrite is also attached to the PCB to form a Faraday cage, efficiently reduce the transmission and reception interference of EM waves.

Adding to that, the structure of BK1608HS220-TV exists in a lead or surface mount mounting format, hence provides the advantages of wider space for installing on bigger board. Moreover, the ferrite material used was of extremely high frequency and possesses large rate of losses, therefore it would effectively transfer heat out of EMI filter.

In conclusion, BK1608HS220-TV EMI filter utilizes both capacitors and inductors to construct the entire device, then provides a series of functions such as surge protection and EMI/RFI reducing. With its leading features, this kind of ferrite beads and chips could totally fit into the demand of wide application of consumer electronics.
