Introduction

EMI/RFI filters are designed to reduce or attenuate electromagnetic interference and radio frequency interference in electronic circuits. These filters are usually employed in an electronic device to limit emissions, or to limit the interference caused by electronic devices to other systems or components.The NFE61HT181C2A9L EMI/RFI filter is a compact, low-cost, RoHS compliant filter designed to reduce the effects of EMI/RFI interference in a wide variety of electronic applications. This filter is an LC (Type 1) RC (Type 2) network, meaning that it uses both inductors and capacitors to provide more efficient filtering than a single network filter.

Application Field

The NFE61HT181C2A9L EMI/RFI filter is designed for use in high-frequency, high-speed switching applications that require an effective and compact solution to EMI/RFI interference. Examples of these applications include AC to DC power supplies, DC-DC converters, LED lighting, motor controllers, industrial amplifiers, switching regulators, and Class D amplifiers. The NFE61HT181C2A9L filter can also be used to reduce EMI/RFI interference in audio and video circuits.

Working Principle

EMI/RFI filters work by reducing the amount of high-frequency interference present in a circuit. This is done by using inductors and capacitors to form an LC (Type 1) or RC (Type 2) network. The inductors and capacitors present in the network form an electrical shield that is able to reduce the impact of high-frequency interference on a circuit.The NFE61HT181C2A9L filter operates on the principle of an LC (Type 1) network, which is composed of an inductor and capacitor in series. This type of filter is known to be more efficient at reducing EMI/RFI interference than a single-component RC (Type 2) filter. The inductor in the LC network acts as a high-pass filter, while the capacitor acts as a low-pass filter. This combination of components allows the filter to reduce both high- and low-frequency interference, providing an effective solution for suppression of EMI/RFI noise.

Conclusions

The NFE61HT181C2A9L EMI/RFI filter is an effective and cost-effective solution for reducing EMI/RFI interference in electronic circuits. It is an LC (Type 1) RC (Type 2) network which is composed of an inductor and capacitor in series, allowing it to reduce both high-frequency and low-frequency interference. The NFE61HT181C2A9L filter is designed for use in high-frequency, high-speed switching applications and is suitable for use in AC to DC power supplies, DC-DC converters, LED lighting, motor controllers, industrial amplifiers, switching regulators, and Class D amplifiers.
