Capacitor tolerance codes are used to indicate the permissible deviation of a capacitor's actual capacitance from its marked value. Here is the capacitor tolerance code chart for your conference: Numeric Code: Two-Digit Code: Directly indicates the capacitance value in picofarads (pF). For example, “47” means 47 pF.

What does 102 mean on a capacitor?

Therefore, a capacitor with the code "102" would have a value of 10 × 10 2 pF, or 1000 pF, which is also equivalent to 1 nanofarad (nF). The "M" at the end represents the tolerance of the capacitor. In this case, "M" indicates a tolerance of ±20%. This means the actual capacitance of the capacitor can vary by up to 20% from the marked value.

What is a 3 digit code on a capacitor?

A three-digit code on a capacitor is a common way of marking the capacitance value. Here's how it works: The first two digits are the significant figures. These are the two numbers that the value of the capacitor starts with. The third digit is the multiplier. It indicates the number of zeros that should be added after the significant figures.
