EMI Filters

EMI/RFI filters provided by FILTEMC are designed according to CCITT international standard, 005ITT 15101-84, 08.03, 《Test Standards of Filter, NetworkDelay Line》and UL1283《Electromagnetic Interference Filters》. EMI filters are passive low-pass filters composed of passive components (L, C, R) , which are based on the theory of impedance mismatch between filter input end. With a filtering range between 10KHz and 30MHz, the power line EMI filters supplied by FILTEMC can effectively suppress the electromagnetic interference along power lines.

Surge Suppression Filters

Surge suppression filters have both surge and filtering functions. Surge class conforms to GB/T 17626.5-2008 / IEC61000-4-5:2005 Standard. Compact structure, cost-effective, safe, convenient, more reliable.

Pulse Group Series EMI Filters

Pulse series EMI filters are specially designed to suppress fast transient pulse interference, which based on the principle that absorption reflection are complementary to each other. Benefit from advanced designed method and many years practical experiences in EMC field, FTES1 series power line filters provided by FILTEMC have excellent attenuation effect of fast transient pulse interference. Suitable for all kinds of household appliances, watt-hour meter, alarm equipment, electric testing equipment, fuel dispenser, other civilian or military measuring or controlling devices  compliance with IEC-61000-4-4 or GB/T17626.4-1998 Standard.

EMC Products for Frequency Converter

Considerable interference signals generated at the input/output end of equipment because of the special operating principle of frequency converters. Filtemc has developed two series products to solve the EMC problem of frequency converter according to its interference characteristics, listed as Input/Output EMI Filters, Input/Output Reactors.


The power line filter produced by Filtemc is designed according to CCITT International Standards, 005ITT 1501-84 ,08 .03, “Test Specification for Filters, NetworksDelay Lines”UL1283 “Electromagnetic Interference Filter”. It is an passive EMI filter composed of passive devices(L, C, R). It uses the impedance mismatch principle between the EMI/RFI filter and the access end. The filter range is 10KHz to 30MHz, which can effectively suppress electromagnetic interference transmitted along the power line.

High Frequency Absorption Components

High frequency absorption components can effectively suppress the interferencefrom 25MHz to 1GHz, combining with common EMI filter, interference at broad frequency range 10KHZ~30MHZ~1GHZ could be attenuated. This kind of products can not only suppress the conducted interference of electronic equipment, but also the radiated interference. High frequency absorption components provided by FILTEMC include 【High Frequency EMI Suppression Ferrite Cores】, 【Three-terminal DC Filters】, PCB hole-through mounting or surface mounting optional, ultra-small dimensions, high performance, easy and fast installation.
