[introduction] filter wave capacitance is having very main effect in switch power source, how to choose filter wave capacitance correctly, the choice that outputs filter wave capacitance especially is the problem that personnel of every project technology cares very. We can see various capacitance on circuit of wave of power source filter, 100uF, 10uF, 100nF, the look with different 10nF is worth, so how do these parameter decide? Filter wave capacitance is having very main effect in switch power source,…

[introduction] valve of two-way brilliant brake is made by material of N-P-N-P-N5 layer semiconductor, external derivative also 3 electrode, its structure is shown like plan institute. Two-way brilliant brake provides the retrorse parallel connection that is equivalent to canal of brake of two one-way brilliant, but have a control pole only. The construction that two-way brilliant brake manages reachs working principle   Valve of two-way brilliant brake is made by material of N-P-N-P-N5 layer semiconductor, external derivative also 3 electrode,…

[introduction] what is voltaic transformer? It is big electric current by changeover of plan certainty ratio the electric equipment of small electric current, call voltaic transformer. The principle is principle of basis electromagnetism induction, voltaic transformer has the coil of two insulation, cover the core that closes in, . Its winding v/LIT all over the ground number is very few, in the circuitry that strings together the electric current that measures in need, accordingly it often has all electric current…

[introduction] capacitor of pottery and porcelain calls porcelain interpose capacitor again or alone stone capacitor. Just as its name implies, porcelain interpose capacitor is the capacitor that medium material is pottery and porcelain. According to material of pottery and porcelain different, the capacitor of interpose of high frequency porcelain that this kind of capacitor can divide the capacitor of interpose of low frequency porcelain that is 1 ～ 300 PF for the capacity and capacity to be 300—22 000 PF…
