Hi reader,
In my board I have used a 22uF/35V tantalum capacitor (125E ESR). It is across the filtered output of bridge wave rectifier. So it is rippled DC. The peak voltage across it is 25V under worst condition.
When I turned on the power supply, the capacitor got burnt immidiately (shorted). Now I am analysing what went wrong? I have checked, max volateg across it, temperature etc. I am told to check the ripple voltage to ripple current. How to measure it with CRO?
Thanks in advance.
