Which is good PR connector _ Xu Song Chong electronic products factory _ Guancheng connector

EMC (Electromagnetic Compatibility) abbreviation EMC, refers to an electronic device not interfere with other devices Guancheng connector, but is not affected by other devices. Electromagnetic compatibility and we are familiar with, like security, is one of the most important indicators of the quality of products. Involving personal and property safety, and electromagnetic compatibility are related to personal and environmental protection. Turns select the whole bundle cable through a ferrite bead constitutes a common mode choke, if necessary, may also be in the ring on top of the cable around a few turns. The more turns on the lower frequency interference suppression, the better the connector where the good PR, while higher frequency noise weak inhibition. In practical engineering, according to the frequency characteristics of the interference current ring to adjust the number of turns. Usually when wide-band interference signals, you can set both on the cable ring, each surrounded by a different number of turns Guancheng magnetic connector of choice, so you can simultaneously suppress high frequency interference and low-frequency interference. Mechanism of action from the point of view of the common mode choke coil, the greater the PR impedance connector factory direct, for interference suppression effect is more obvious. The common mode choke coil impedance from the common mode inductance Lcm = jwLcm, from the formula is not difficult to see that, for a certain frequency noise, magnetic inductance bigger the better. But the reality is not the case, because there is an actual ring parasitic capacitance, and its existence is parallel with the inductor. When faced with the high frequency noise, capacitive reactance is small, the magnetic inductance short circuit, so that the common mode choke useless.
