How do you read capacitor colors?
How do you read capacitor colors?
The capacitors use a capacitor color code similar to the resistors color code (3, 4 or 5 bands). The first two colors indicate significant digits of the value of the capacity (in pF), the next colour is the corresponding power of 10, the other two colors are optional and indicate tolerance and maximum voltage.
Does color of capacitor matter?
Each color painted on the capacitors body represents a different number. The color codes used to represent the capacitance values and capacitance tolerance is similar to that used to represent resistance values and resistance tolerance. Generally, the capacitors are marked with four or more color bands.
What is Colour code system of capacitor?
Capacitor Voltage Colour Code Table
| Band Colour | Voltage Rating (V) | |
|---|---|---|
| Orange | 15 | 400 |
| Yellow | 20 | 500 |
| Green | 25 | 600 |
| Blue | 35 | 700 |

How big is an elmenco compression trimmer capacitor?
Elmenco compression trimmer capacitor. Bank of 5. 1.5 – 8 pF @ 350v. 1 side of each cap soldered to bracket for common ground. May be un-soldered. 2-1/2″ mounting centers. 1″W x 3/4″H. Elmenco compression trimmer capacitor. 2 – 15 pF, 175v.
How many Pico farads are in trimmer capacitors?
To improve the precision of the capacitance values, simple gear mechanisms can be used that allow multiple turns between the lowest and highest settings. The value of trimmer capacitors is less than 100 pico farads. Trimmer capacitors are commonly used in various RF, VHF and microwave frequency band circuits.
