How do you read a 3 digit capacitor code?

The three-digit capacitance code works as follows:

1. If the third digit is 0 through 6, add that many zeroes to the end of the number. (For example, 453 → 45 x 103 → 45,000.)
2. If the third digit is 8, multiply by 0.01. (e.g. 278 → 27 x 0.01 → 0.27)
3. If the third digit is 9, multiply by 0.1. (e.g. 309 → 30 x 0.1 → 3.0)

What are the three numbers on a capacitor?

If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero.

How to read the ceramic capacitor code value?

1 Ceramic disc capacitors have two to three digits code printed on them. 2 The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. 3 When the first two numbers are multiplied with the multiplier, the resulting value is the value of the capacitor in picofarads.

What are the first two digits of a capacitor?

The first two significant digits represent the first two digits of the actual value, which is 47. The third digit is the multiplier, which is ×1000. The letter J signifies the tolerance of ±5 %. Since this is the EIA coding system, the value will be in pico farads. Hence the value of the capacitor above is 47000 pF ±5 %.

What does the Mark mean on an electrolytic capacitor?

Traditionally, this mark designates the – end on an aluminum electrolytic capacitor (which are usually shaped like tin cans). On tantalum electrolytic capacitors (which are very small), this mark designates the + end. (Disregard the bar if it contradicts a + or – sign, or if it is on a non-electrolytic capacitor.)

What is the tolerance of a ceramic capacitor?

The letter J signifies the tolerance of ±5 %. Since this is the EIA coding system, the value will be in pico farads. Hence the value of the capacitor above is 47000 pF ±5 %. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board.
