Capacitor Colour Code Values with Examples

Tolerance represents how much more or less you can expect capacitors actual capacitance to be from its rated capacitance which is printed on the capacitor. Tolerance rating is expressed as plus (+) or minus (-) value in ± Pico farads for low value capacitors which are less than 100pf or as percentage (± %) higher than 100pf for high value capacitors. It can …

Motor Capacitor FAQ

Voltage - Voltage can have an exponential effect in shortening the design life of a capacitor. A run capacitor will have a marked voltage rating that should not be exceeded. For example, a capacitor is rated for 440 volts. At 450 volts, the life may be reduced by 20%. At 460 volts, the life may be reduced by 50%. At 470 volts, there is a 75% ...

Color and Alphanumeric Value Coding of Capacitor

So, a capacitor marked as ''10uF 25V K'' would be a 10 microFarad capacitor, with a voltage rating of 25 volts and a tolerance of ±10%. Special Considerations for Specific Capacitor TypesDifferent types of capacitors, such as electrolytic, ceramic, or tantalum, may have variations in their alphanumeric coding. Electrolytic capacitors, for instance, often have their …
