Electromagnetic compatibility (EMC) is a capability of device or of system to exercise a normal working efficiency in conditions of being influenced by other natural or artificial signals and simultaneously not being an source capable to influence other electronic devices by its own electromagnetic field or to emit any signals disturbing an operation of such devices.
Effect of electromagnetic energy extraction by any equipment is called an electromagnetic emission.. A series of undesirable effects (from noises in TV screen to failures in on-board airborne electronics or in medical equipment) may be caused by operation of different electronic devices.
In order to protect equipment and devices from harmful effects of electromagnetic emission of other electric and electronic devices and also of natural phenomena, a wide nomenclature series of materials is developed and different configurations of ferrite cores are developed.
CF series noise suppressing ferrite cores consist of two halves of noise suppressing ferrite that are mounted within plastic casing. CF cores are set up and fixed on protected wire by means of latch.
T-ring- and RH-tube-configured NiZn ferrite cores are intended for protection from high-frequency noises.. It is recommended to use the cores with wires and cables having a plastic insulation sheath .
FH series ferrite transfluxors are intended for suppression of noises in plug-in connectors of data transmission links.
RP-configured noise-suppressing flat ferrite cores are intended for suppression of noises in flat multi-wire cables of FFC or PFC type.
FP series noise-suppressing ferrite plates are intended to attenuate noises of micro-processors and to decrease their mutual influence.
FAT100 series ferrite absorbing plates of П100*100*6,3 and П100*100*5,3 type are intended to make an echo-less chambers and overhearing protected rooms.
FAT 900 series NiZn ferrite absorbing plates of П100*100*4,3 type provide a maximum of signal suppression at a cellular mobile communication frequency of 900 MHz and are intended for screening VHF radio-frequency range signals, mobile cellular communication and TV signals.
FAT-DL series NiZn ferrite absorbing elements are specially developed for making compact echo-less chambers having a protected range from 30 MHz to 2 GHz. These elements are two П100*100*3 plates separated by a gap of 21 mm.
Wideband pyramid-shaped WPA series absorbers combined with FAT series ferrite plates of П100*100*6,3 type are intended for making echo-less chambers and are characterized by high noise suppression in frequency range from 30 MHz to 18 GHz.
FAM series flexible absorbers are intended for protection from Electromagnetic interferences (EMI) in frequency range from 30 MHz to 25 GHz. Advantages of their using are simplicity of their processing and ease of their shaping.
APG series granulated plastic absorber contains a high percent of absorbing ferrite and intended for making complex profile absorbers by extrusion method.
