I'm using a AC-DC power supply to provide 24VDC input to a PCB. A 100uF,35V tantalum is used as one of the filter capacitors for the 24V(same from supply) input of DC-DC regulator on PCB. In some cases, this 35V tantalum capacitor goes bad and gets shorted and damages the PCB. I'm trying to find the root cause for this.
When looked at the datasheet of AC-DC power supply, one of the output parameter is as below
"Transient Response Recovery -<6% or 300mV of set voltage for 50% load change (above 25% load),500μs for recovery to 1% or 100mV of set voltage"
What does this specification mean?
Can the 24VDC output from power supply damage the 35V rated tantalum capacitor?
