EMI Filter Kits: EKEMBL03E Application Field and Working Principle

EMI (Electromagnetic Interference) Filter Kits are essential components used to reduce the radiation generated by electronic equipment. The EKEMBL03E is a filter kit manufactured by TDK-Lambda, which is designed to reduce interference on power line signals. It is suitable for a wide range of applications, including commercial, industrial, and consumer products.

I/O (Input/Output) Operation and Specifications

The EKEMBL03E is designed with four DC main input/output terminals. The four terminals are labeled A-G, which correspond to the DC main input/output. Each of the terminals has an independent current detection and overload protection circuit. The filter kit is designed with a minimum input/output impedance of 20 kHz, and a maximum bandwidth of 1.0 GHz. The maximum continuous input current per terminal is 10 A, and the maximum total continuous input current is 50 A. The filter kit can also be operated at an ambient temperature of up to +85 °C and a relative humidity of up to 95% RH.

Filter Characteristics: EMI Suppression Performance and Circuit Design Principles

The EKEMBL03E is designed to achieve a wide range of EMI suppression performance. It is able to reduce interference on a power line signal with up to 1.0GHz bandwidth, with a ±3dB cut-off frequency of 1.3 GHz. The EMI filter is also designed to meet the requirements of EN61000-4-3:2016 and CISPR Standard 16-1-4:2016. The filter kit consists of a combination of common-mode and differential-mode inductive elements. The common-mode inductive elements are designed to reduce the common-mode radiation, while the differential-mode inductive elements are designed to reduce the differential-mode radiation. In addition, the design utilizes several capacitive elements to reduce the differential-mode and common-mode conducted emissions below the cable.

Mounting Configuration and Application Examples

The EKEMBL03E is designed to be mounted on a PCB, and has a maximum size of 67.4 mm x 46.9 mm x 35.5 mm. The filter kit can be used in a variety of applications, including communications equipment, industrial machinery, multimedia devices, and consumer products.

Conclusion

The EKEMBL03E is a filter kit designed to reduce interference on power line signals. It is designed with four DC main input/output terminals, and is able to reduce interference with up to 1.0GHz bandwidth. The filter kit is suitable for a wide range of applications in commercial, industrial, and consumer products.
