Ceramic Capacitor Code

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

What is ceramic capacitor code?

Ceramic capacitors encoding consists 1-3 digits. If the capacitor code consist only 1 or 2 digits, it is simply their capacitance value in PicoFarads (pF). For example if a ceramic capacitor has a code '5' and other has '47', their respective capacitance values are 5 pF and 47 pF.

What is 0.1 uF capacitor code?

Picofarad (pF)	Nanofarad (nF)	Microfarad (uF)
33000	33	0.033
47000	47	0.047
68000	68	0.068
100000	100	0.1

What does 104 mean on a capacitor?

The third digit indicates the number of zeros you have to write after the first two-digit. For code 104, the third digit is 4, so you have to write 0000 (4 zeros) after the 10 (first two-digit). So the capacitance value for 104 will be 100000 picofarads or 100 nanofarads or 0.1 microfarad.

How are ceramic capacitors marked?

The Ceramic Caps The value is printed on each in a three-digit code. This code is similar to the color code on resistors, but uses digits instead of colors. The first two digits are the two most significant digits of the value, and the third digit is the exponent on the 10.

How do you read a capacitor code?

The first two numbers represent the value in picofarads, while the third number is the number of zeroes to be added to the first two. For example, a 4.7 μF capacitor with a voltage rating of 25 volts would bear the marking E476. This translates to 47000000 pF = 47000 nF = 47 μF.

What does 1uF mean?

A: uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F. Dannie Musser.

What is the difference between C0G and X7R?

C0G is a Class 1 dielectric, so it's not included (more on this later). X5R and X7R are in Class 2, and Y5V is in Class 3. The first character indicates the lowest temperature that the capacitor can handle. The letter X (as in X7R, X5R) corresponds to –55°C.

What is 105J 400V capacitor?

1uF/400V (1000nF -105J) – Polyester Film Capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field.

What is 474k capacitor?

470nF/400V (0.47uF – 474k) – Polyester Film Capacitor A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field.

What does 102 mean on a capacitor?

9. 0,1. For example: A capacitor with the number 102 printed on it means a 10 with two zeros. The value in this case is 1.000 pF or 0,001 µF also named 1 nf. More examples below.

What does 473 mean on a capacitor?

This is a 0.047uF - (473) Ceramic Capacitor Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc.

What does 103 mean on a capacitor?

The example capacitor has a 3 digit number printed on it (103). The first two digits, in this case the 10 give us the first part of the value. The third digit indicates the number of extra zeros, in this case 3 extra zeros. So the value is 10 with 3 extra zeros, or 10,000.

What is a 224 capacitor?

It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. Single layer disc, resin coated with through-hole leads. Specification. Ceramic 224 Capacitor. Capacitor value: 0.22uF / 220nF.

How do you identify a capacitor?

Generally the first two digits indicate the capacitors value and the third digit indicates the number of zero's to be added. For example, a ceramic disc capacitor with the markings 103 would indicate 10 and 3 zero's in pico-farads which is equivalent to 10,000 pF or 10nF.

How do I know if my ceramic capacitor is valuable?

Ceramic capacitors usually uses 3 digits like 102, 103, 101 for indicating their values and the values are in term of Pico farad. The numbering system is easy to use, if you remember it is based on picofarads, not microfarads. If a ceramic capacitor has three digits – ABC, then the value would be AB*10^C Pico Farad.

How are capacitors labeled?

The value of the capacitor is denoted in picofarads for ceramic, film, and tantalum capacitors, but for aluminium electrolytic capacitors the value is denoted in microfarads. For small values the letter R is used to denote a decimal point, e.g. 0R5 is 0.5, 1R0 is 1.0 and 2R2 is 2.2, etc..

What does K and j mean in capacitor?

K means that the capacitance tolerance is 10% (F=1%, J=5%, K=10%. These are most common resistance and capacitance tolerances). MF does not mean Micro Farad. Probably it stands for Metallized Film, which indicates the capacitor type/material.

What numbers matter on a capacitor?

The higher the voltage rating on your capacitor (or other electrical item) the faster the electrical current moves. The second rating is the microfarad (MFD) rating. A microfarad is a term to describe a capacitor's level of capacity. That means the higher the microfarad rating, the more electrical current it can store.

How do I identify a ceramic SMD capacitor?

Often a SMD device will have it's value encoded in the form of numbers and letters, made by a laser marking system. 4.7U indicates a 4.7 microfarad part while 3.3 P is the marking for a 3.3 picofarad capacitor.
