# How do you read a ceramic capacitor value?

## How do you read a ceramic capacitor value?

The value is expressed in terms of pico-Farads. To decode the value, take the first two digits, then follow them with the number of zeros indicated by the third digit. 104 becomes “10” followed by “0000,” or 100000 pF, more succinctly written as 100 nF.

How do I read a capacitor with a multimeter?

To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. Touch the meter leads to the corresponding leads on the capacitor, red to positive and black to negative. The meter should start at zero and then moving slowly toward infinity.

What does J mean in capacitor?

A capacitor that has a decimal is typically measured in uF. For example: .47 = .47 uF = 470 nF. The letter on a capacitor designates the tolerance. J = +/- 5% K = +/- 10%

### What is the value of ceramic capacitor 104?

0.1uF
This is a 0.1uF – (104) Ceramic Capacitor Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc.

How do you identify ceramic capacitors?

Ceramic types of capacitors generally have a 3-digit code printed onto their body to identify their capacitance value in pico-farads. Generally the first two digits indicate the capacitors value and the third digit indicates the number of zero’s to be added.

What is the use of a ceramic capacitor?

Ceramic capacitors are used in electronic sensor circuits. Ceramic capacitors are used in electronic signal transmitter and receiver circuits. Ceramic capacitors are used in audio mixer, controller, equlizer circuits.

#### What is the value of a capacitor?

Capacitor values can be of over 10 9 range, and even more as super capacitors are now being used. To prevent confusion with large numbers of zeros attached to the values of the different capacitors the common prefixes pico (10 -12 ), nano (10 -9) and micro (10 -6) are widely used.

What is a disc capacitor?

disk capacitor. [′disk kə‚pas·əd·ər] (electricity) A small, flat, circular capacitor that usually has a ceramic dielectric .

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. Ceramic disc capacitor codes are always measured in pico Farads or pF.

What does 1000 uF mean on a capacitor?

The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing.

## What is the value of a ceramic capacitor?

Ceramic capacitors are usually made with very small capacitance values, typically between 1nF and 1µF, although values up to 100µF are possible.

What is the value of 104 ceramic capacitor?

Electronics Components: How to Read Capacitance Values on a Capacitor

Marking Capacitance (pF) Capacitance (ìF)
473 47,000 pF 0.047 ìF
104 100,000 pF 0.1 ìF
224 220,000 pF 0.22 ìF
474 470,000 pF 0.47 ìF

What does uF stand for on capacitor?

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 use of ceramic capacitor 104?

This is a 0.1uF – (104) Ceramic Capacitor Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc. It is always a good idea to put one of these next to the power pins of a microcontroller.

What is the function of ceramic capacitor?

Ceramic capacitors are mainly used for high stability performances and wherein devices with low losses. These devices provide very accurate results and also the capacitance values of these capacitors are stable with respect to the applied voltage, frequency and temperature.

Is there a positive and negative side to a capacitor?

Electrolytic capacitors have a positive and negative side. To tell which side is which, look for a large stripe or a minus sign (or both) on one side of the capacitor. The lead closest to that stripe or minus sign is the negative lead, and the other lead (which is unlabeled) is the positive lead.

#### What is the UF code for a capacitor?

Some capacitors are only marked as 0.1 or 0.01, mostly in these cases the values are given in uF. Some small capacitance capacitors can be marked with an R between numbers. If code is 3R9 then R is an indicator of values Less than 10pF and has nothing to do with resistance. 3R9 would be 3.9pF.

What are the capacitor values on a ceramic disc?

Ceramic Disc Capacitor Values / Code / Label 1 Standard Capacitor Values. Here is a list of the currently available ceramic disc capacitors consisting of standard values. 2 Voltage Code. The brown coloured ones usually have an underline below the marking, which means 50 V / 100 V. 3 Temperature Code.

What is the capacitor code in picofarads?

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.

## How to calculate the capacitor value of a 3 rd code?

As first two digits are 10 and the 3 rd digit is 4, so multiplier factor is 10000, the total capacitance value in pF is as follows: 10*10000 = 100000 pF. Similarly if the capacitor code is 152, the 3 rd digit is 2 so multiplier factor is 100. The capacitance value will be calculated as follows: 15*100 = 1500 pF.
