Electromagnetic interference (EMI) and radio frequency interference (RFI) filters are essential components of many consumer, industrial, medical, automotive and military electronic systems. There is a wide range of available filter technologies, including LC, RC networks, capacitors, inductors and other passive components. The NFL18ST157X1C3D is a common and versatile EMI/RFI filter, designed to attenuate both EMI and RFI as well as reduce susceptibility to either.

The NFL18ST157X1C3D filter is a compact, snap-in solution with fixed capacitance values for added attributes, such as high current handling, low insertion and return losses, and snap-in installation. Its application fields include AC/DC switching power supplies, AC motors, variable frequency drives, AC/DC panel boards, consumer electronics, and more.

The NFL18ST157X1C3D filter works by combining the filtering properties of a capacitor-inductor-resistor (LCR) network. The low series resistance of the LCR helps to attenuate noise which rides the power line while the series inductor helps to reduce conducted EMI emission on the power line. The filter utilizes an EMI inductor to block noise from entering the load side, while the capacitor-inductor-resistor network helps to prevent radiated EMI emission on the input side. Additionally, the filter also includes an EMI capacitor to reduce the conducted EMI emission from the load side.

The NFL18ST157X1C3D filter offers advantages such as low insertion and return losses, broadband filtering, high current ratings, and a snap-in installation for easy mounting. It is designed to minimize voltage drops on the line, reduce ground loop currents and harmonic distortion, and provide galvanic isolation from the ground. Furthermore, it-is usable over wide temperature and frequency ranges.

In conclusion, the NFL18ST157X1C3D filter is a high-performance, energy efficient EMI/RFI filter with several key features and benefits. It is an ideal choice for applications that require reliable noise filtering and low losses. It can be used in a variety of applications such as AC/DC switching power supplies, AC motors, variable frequency drives, AC/DC panel boards, and consumer electronics.
