EMI/RFI Filters (LC, RC Networks) is important in order to protect electronic components and systems against electromagnetic interference (EMI) and radio frequency interference (RFI). The KNF21100C65DA3TS is an EMI/RFI filter designed for protecting electronics from contacting external electromagnetic interference. It is a type of RC network filter. This article will discuss the application field of KNF21100C65DA3TS and the working principle of its RC network filter.

The application field of KNF21100C65DA3TS is broad and diverse. This filter is suitable for a variety of electronic devices, ranging from consumer products such as mobile phones and computers to industrial automation control systems and power equipment. Due to its high quality of EMI/RFI protection, the KNF21100C65DA3TS filter is especially popular in medical equipment and automotive industry, where radiations, sparks, electric arcs, etc., are present continuously, and EMI/RFI protection is of great importance.

KNF21100C65DA3TS is an RC network filter. The RC network stands for resistor-capacitor network, which can be used for various filtering purposes, such as removing unwanted noises from signals and EMI/RFI suppression. It mainly consists of a resistor, a capacitor, and an inductor. The resistor and capacitor are connected in series, while the inductor is connected in parallel. It primarily works by providing a path for high-frequency signals to be diverted away from the circuit, and it can also reduce noise from low-frequency signals.

The working principle of RC network filter for the KNF21100C65DA3TS can be understood through the impedance, which is a measure of the opposition of a circuit to the flow of current. The impedance of the RC network is calculated by multiplying the resistor and the capacitor, which is proportional to the frequency. Thus, at higher frequencies, the impedance would become higher and the EMI/RFI signals would be diverted away. At lower frequencies, the impedance would become lower, and the noise would be filtered out.

In conclusion, the KNF21100C65DA3TS filter is a type of RC network filter, mainly designed to protect electronics from EMI/RFI. Its application field is wide and diversified, while its working principle is based on the impedance of the resistor and capacitor in the RC network. Therefore, it effectively provides excellent EMI/RFI protection to electronic devices and systems.
