Failure mechanisms in ceramic capacitors

In-circuit tests can rarely apply sufficient voltage and/or time for realistic IR measurement The electrical problem may be intermittent, with the failure masked during manufacture as a result of thermal treatment or by probe pressure, but failing later Most functional tests are not sensitive even to the omission of capacitors used

When should I use a low ESR capacitor

When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed …

What are some reasons to connect capacitors in series?

I have only seen it done to increase voltage. On some power supply front-ends (AC/DC conversion) with a voltage doubler the capacitors are in parallel at low voltage and in series at high voltage. This works out well since for a constant power out the current is double at the lower voltage. As you mention balancing resistors are required.

What Is A Typical Sign That A Capacitor Is Bad Or Has Failed?

Voltage Rating: If a capacitor cannot handle the voltage applied to it, it may fail prematurely. This is often due to selecting a capacitor with a voltage rating too close to the operating voltage. Current Capacity: Similarly, capacitors have a maximum current capacity. Exceeding this capacity can lead to overheating and failure.
