The KNF21400C17DA3TS is an EMI/RFI filter that is used to reduce electrical noise in electronic circuits. This filter is a two-stage filter, with a low-pass network and a high-pass network. The filter is made up of two capacitors and two inductors that are connected in parallel with each other. This helps to reduce the electrical noise that is present in the circuit. The filter is designed to reject frequencies from 9 kHz to 30 MHz.

The application fields of the KNF21400C17DA3TS are primarily related to the automotive industry. This filter can be used in automotive electronics to reduce the level of electrical noise that is present. In addition, it can be used in industrial and medical electronics applications. It can also be used in aeronautical applications and in radio and television broadcast systems.

The working principle of the KNF21400C17DA3TS is relatively simple. It works by blocking or attenuating the frequencies from 9 kHz to 30 MHz. This frequency range is where the most common sources of electrical noise are. As the frequencies move through the filter, they are attenuated or blocked, leading to reduced electrical noise. The filter also has a low-pass network, which helps to reduce the high frequency noise.

The KNF21400C17DA3TS is a great choice for EMI/RFI applications in the automotive industry. It is easy to install and provides excellent attenuation of the frequencies that can cause electrical noise. It has a low-pass network that helps to reduce the higher frequency noise, and it is designed to reject frequencies from 9 kHz to 30 MHz. With its two-stage filter system, it is a great choice for automotive electronic applications.
