Filter Capacitor

The capacitor on the circuit board adopts double filtering, so that the interference of the signal can be avoided effectively ;
The filter capacitor is used in the power rectifier circuit to filter the AC component. Make the output DC smoother. Moreover, for the precision circuit, the parallel capacitor circuit is often used at this time to improve the operation efficiency of the filter capacitor.

Black ring high frequency low resistance capacitor

The electrolytic capacitor in the switching power supply output filter, the saw-tooth wave voltage frequency up to tens of kHz, or even dozens of MHz, the capacity is not the main index, measure the merits of the capacitance standard is "impedance" characteristics, require the equivalent impedance of low frequency to work in switching power supply in high frequency at the same time for peak signal generated from semiconductor devices has good filtering effect.

Pure copper filter

A device that eliminates input noise or noise by filtering input or output into pure direct current. A circuit that filters the frequency point of a particular frequency or the frequency outside the frequency point is a filter whose function is to obtain a particular frequency or to eliminate a particular frequency.

Nickel plated protective cover

The hollow nickel plated protective cover is provided with an outer net shaped radiating hole, and the heat dissipation is good, and the movement of the core can be protected, and the utility model can be used for a long time;
