Open mode failure An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit. For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is …
Replacing Capacitors in Old Radios and TVs
Note that two of these types—mica capacitors and flat molded paper capacitors—look similar. Both are flat, often with color coding dots to indicate the value. It is easy to tell them apart by checking the value. Mica capacitors have very small values, typically under .001 mfd., typically under .001 mfd.
