Multilayer Ceramic Chip Capacitors High Voltage MLCC

Multilayer Ceramic Chip Capacitors High Voltage MLCC

Have you ever come across power problem where once you activate the power supply and the fuse blow? You might have checked all the parts in the power (main) and secondary section and all the elements looks fine! Where’s the problem? A fuse blown are usually the result of a shorted bridge rectifier, defective posistor, power transistor or FET, shorted primary winding of switch-mode power transformer, shorted etc.

I got frustrated as to where is power problem’s cause. Every time when I activate the power supply the fuse strike promptly (the fuse became dark colour and this signify that a major short-circuit is in the). I cannot discover to blame and have assessed all the parts in the power! The triggered of the difficulty was finally uncovered by me. Figure what? It was the primary filter capacitor (220 microfarad 400 volt). After replacing the filter cover the power-supply operated absolutely fine. I start my detective work to figure out why the fuse can be triggered by this multilayer ceramic chip capacitors high voltage MLCC to blow even though I already confirmed it OK with my meters.

The meters which I used to check the filter cover were esr meter, digital capacitance meter and analog meter. In this article I am not going to describe about how you can assess multilayer ceramic chip capacitors high voltage MLCC or screening capacitor and just how capacitor function. I considered many of you understand how exactly to check multilayer ceramic chip capacitors high voltage MLCC and additionally usually utilizing such metres. Measured with analogue it revealed capacitor charging and discharge, with electronic capacitor tester it showed around 220 microfarad and with esr meter it revealed reduced reading!

This demonstrated the awful multilayer ceramic chip capacitors high voltage MLCC breakdown when under full operating voltage. Then, how can I confirm that this multilayer ceramic chip capacitors high voltage MLCC is faulty? By utilizing an insulation tester that is analogue. After I join the cap that was faulty to the meter and push the go button -it showed an incredibly low-resistance and this can be the when voltage applied demonstrated of short circuit between the menu,! There isn’t anything related to electrolyte that is poor. A capacitor that is good will merely showed discharge and a charge in the insulating material meter just like multilayer ceramic chip capacitors high voltage MLCC is being checked by you utilizing multimeter that is analog. In the marketplace there is quite a number of ranges that you can purchase. It has the variety of 100v 50v, 250 v, 500v, v that is 1000 as well as 5000v v! If you’d like to examine multilayer ceramic chip capacitors high voltage MLCC of 100 microfarad you need to choose 100v. 250v will blow your multilayer ceramic chip capacitors high voltage MLCC which is under evaluation, if you select it from www.sh-jinpei.com.
