Electro-magnetic interference (EMI) and radio frequency interference (RFI) filters are employed in a wide variety of equipment, from cell phones to medical imaging devices to minimize the impact of electrical interference. The KNF21400-W3 is a filter designed for high-powered applications requiring electrical and mechanical protection from EMI and RFI. It is a quad shield EMI/RFI filter, with four layers of shielding, made from a combination of metal and dielectric material. The four layers of shielding are designed to reduce the amount of EMI and RFI that can enter and exit the equipment.
The KNF21400-W3 employs a combination of inductors and capacitors to create a low-pass filter, which blocks single-frequency interference and attenuates these frequencies. Inductors are coils of wire, wrapped around some type of magnetic core material, that store energy and then release it in a controlled way, creating a magnetic field. Capacitors, on the other hand, store electrical energy, much like a battery, and then release it in a controlled way, creating an electric field.
The low-pass filter in the KNF21400-W3 ensures that only low-frequency signals, such as audio or radio signals, are allowed to pass through the filter. High-frequency signals, such as EMI and RFI, are blocked and attenuated at the filter’s terminals. The filter also employs a metal screen shield to further reduce the amount of interference that can pass through.
The filter is also designed in such a way that it provides superior durability, with an IP66 dust and water resistance rating. It also has a very high temperature range, up to 125°C, allowing it to be used in high-power applications. Lastly, the KNF21400-W3 has a very low insertion loss, meaning that it causes minimal signal loss as it filters out unwanted interference.
In summary, the KNF21400-W3 is a filter specifically designed for high-power applications requiring electrical and mechanical protection from EMI and RFI. The filter employs a low-pass filter with a combination of inductors and capacitors, as well as a metal screen shield, to reduce the amount of EMI and RFI that can enter or exit the equipment. The filter also provides excellent durability and a wide temperature range, and has a very low insertion loss.
