I am using the connections as attached.
The part is a printer and it works on 8V (Consider) and the current drawn depends on what we print. If its all black print, it will draw more current and less current if its only text so on (Depending on strobe activated each time)
Maximum it can take is 2.5Amps/stobe and to acheive max we activate 3 strobes (example) so the worst case maximum current will be 7.5A. (there could be surges etc while printing which is very difficult to see on a CRO I have and I am infact not even sure if it exists)
The ceramic capacitors works fine but after a period of time (Few days or months), the capacitor is short and we need to replace.
What could be the possible reasons for this? Am I selecting a wrong capacitor or is it something else that can cause this.
The capacitor used is X5R
