Y series circular filter electric connector belongs to the low passed filter connector that is used to resist electromagnetic interference by cutting off the broadcasted route of the signal lines of electromagnetic interference and power lines. It composes the perfect electromagnetic interference defending with shielding to defend electromagnetic interference effectively. According to its usage it is divided into single lines EMI filter, the power source EMI filter and so on several kinds. Generally divides into single capacitance(C type), the single electronic inductance (L type), T type and “pai” type and so on according to the form of circuit. Y series circular filter electric connector has the electric appliance performance ascendance , high reliability and so on merits, it can be widely used in the domains of short wave, ultra short wave as well as microwave communication equipments, and testing system.

Y series circular filter electric connector has used the high reliable pianhuang structure or the single leaf rotating hyperbolic xianhuang contacts pair; The connecting style of the plug and the receptacle is the coupling of three spiral bayonet, and it has quick connection and quick separation 2 merits. What’s more, it has five-key guide to avoid mis-mating to assure right connection. The ports of the input and output of the filter inside is separated by the connecting ground plate to effectively prevent reducing of the filter characteristic because of the xianluouhe.

·The filter coupling must install in the metallic shield box, and mustuse the electromagnetism sealing packing?

·When filter coupling lead wire foot , continuously welds thetime not to be able to surpass for 5 seconds?

Users type in the selection, should consider ordinary Connector electrical parameters and environmental parameters, or for more information to help me plant selection and specialized production, should provide the following general parameters, operating voltage, and the cutoff frequency capacitance is more important.

 

1, operating voltage : AC (V) or DC (V)    2, the current : AC (A) or DC (A)
3, the cutoff frequency : MHz                   4, capacity : PF
5, equipment impedance :  O                   6, frequency interference suppression : MHz

   The filter coupling filter performance is selects when the filtercoupling the key indicator, the cut-off frequency of filter must behigher than the signalling frequency which on the electric cable musttransmit; The filter 3dB insertion loss corresponds frequency forcut-off frequency. When order product attributed the filtercharacteristic with the filter code, table 1 has produced thedifferent filter code correspondence filter characteristic.

According to the special details, may use three methods to determinethe cut-off frequency: Simulated signal: The signal frequency must be lower than the cut-offfrequency. Pulse signal: If rises/the fall time is tr, then 1/ tr is smaller thanthe cut-off frequency. Pulse signal: If the pulse signal repetition frequency is f, then 15fis smaller than the cut-off frequency.
