• EMI filters provided by FILTEMC are designed according to CCITT international standard, 005ITT 15101-84, 08.03, 《Test Standards of Filter, Network and Delay Line》and UL1283《Electromagnetic Interference Filters》. EMI filters are passive low-pass filters composed of passive components (L, C, R) , and are based on the theory of impedance mismatch between filter and input end. With a filtering range between 10KHz and 30MHz, filters supplied by FILTEMC can effectively suppress the electromagnetic interference along power lines.
  • Considerable interference signals generated at the input and 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 Filters】, 【Input/Output Reactors】.
  • PCB micro-filter is specially designed for ultra-thin electronic device, with the properties of small dimension, wide range and high filtering effect, specially suitable for interference suppression of each branch of equipment internal circuit because of its size and function advantage.. We can provide flexible customized solutions of different dimensions and different filtering effect according to customers' requirement regarding their equipment inner space.
  • High frequency absorption components can effectively suppress the interference from 25MHz to 1GHz, combining with common EMI filter, interference at broad frequency range 10KHZ~30MHZ~1GHZ could be attenuated. This group 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 and easy and fast installation.
