**capacitor**. there**are**two common engine types**capacitors**, run**capacitors**and launch**capacitors**. The units of**capacity are**labeled in microfarads (µF). Older**capacitors**possibly with the obsolete terms “**mfd**” ,the**means microfarads**and “**MFD**”**means**millifarad.What is the value of a capacitor labeled 102 here?

How to read capacitor values?

**method 2**

**Reading compact capacitor codes**

- Write down the first two digits of the capacity.
- Use the third digit as a zero multiplier.
- Calculate the capacity units from the context.
- Instead, read codes that contain letters.
- Read the tolerance code on ceramic capacitors.
- Read letter-number-letter tolerance values.

What is the tolerance of the capacitor?

**capacitors**are rated according to how close their actual values are to the rated nominal values

**capacity**used with colored bands or letters to indicate their actual

**tolerance**. The usual

**tolerance**Variant for

**capacitors**is 5% or 10% but some plastic

**capacitors**are evaluated with only ±1%.
