EMI/RFI Filters are critical in the area of electrical engineering, as their main purpose is to protect electronics and data from electromagnetic interference. The KNA21220C25UA3TS filter integrates a low and high pass filter, providing the highest level of shielding from such interferences. The KNA21220C25UA3TS filter has proven to be especially useful in the field of automotive, aviation and industrial applications.

The KNA21220C25UA3TS filter works by restricting the electromagnetic signal noise from interfering with sensitive radio frequencies. As a result, it can reduce or eliminate EMI that would otherwise affect the performance of electronic products. The filter uses a combination of input noise filter, low impedance, hi-pass filter, a high impedance, and an internal power resistor for maximum shielding. The filter is able to effectively supply up to 25A in automotive applications, making it useful in a wide range of applications.

The KNA21220C25 UA3TS can be used in a variety of applications, such as automotive, aviation and industrial applications. In automotive applications, the filter is used to protect ECU (Engine Control Units) systems, TV systems, radio systems, airbag systems, brake systems, audio systems, power windows, and many more. In aviation, the filter is used to protect the aircraft\'s interior from potentially damaging EMI that can interfere with the aircraft\'s avionics and other systems. In industrial applications, the filter is used to protect sensitive equipment and data from EMI arising from the production environment.

The working principle of the filter is based on the principles of low pass and high impedance filters. The low pass filter is used to reduce the amplitude of higher frequency signals while allowing lower frequency signals to pass. A high impedance filter is used to reduce or eliminate the passage of EMI that would otherwise affect the performance of the system. The power resistor provides additional EMI shielding by reducing the level of EMI present.

The KNA21220C25UA3TS filter is a great solution for protecting sensitive electronics and data from EMI and RFI. With its high filtering ability, it can effectively reduce or eliminate electromagnetic interference that could otherwise affect the performance of a system. This makes it a valuable asset for automotive, aviation and industrial applications.
