EMI/RFI filters (LC, RC networks) are used in a variety of applications, and the KNH21104-3AA is no exception. The device is commonly used in the aerospace, defense, industrial and consumer markets for applications such as DC-DC converters, switch mode power supplies, cable assemblies and automotive systems.

This type of filter is designed to reduce electromagnetic interference (EMI) or radio frequency interference (RFI) generated by electronics. EMI/RFI filters may also be used to separate two electric circuits, or to provide a common ground between two circuits, or to prevent noise from entering or leaving a device. It is essential that the filter be designed properly in order to achieve the desired level of attenuation of unwanted electrical noise.

The KNH21104-3AA is a low-profile, 3-pole, snap-in mount filter. It is ideal for applications that require a compact size but still need the protection of a high-performance filter. The device can be used in a variety of configurations, such as DC-DC converters, switch mode power supplies, cable assemblies, and automotive systems. The filter is rated for a maximum voltage of 125V, a maximum current of 10A, and a maximum frequency of 1MHz.

The KNH21104-3AA features a built-in capacitor which effectively doubles the filter’s attenuation level. The filter employs a low-pass RC configuration with a low impedance at high frequencies which helps significantly reduce EMI/RFI on the input and output of any device. This filter also provides an enhanced level of ESD protection should any sudden electrostatic discharge occur.

The KNH21104-3AA presents a cost-effective solution for all of your EMI/RFI needs. The device’s low profile and compact size make it ideal for applications where space is at a premium but still in need of today\'s highest performance EMI/RFI filtering. The filter is designed for long-term reliability and is backed by a five-year warranty.
