How do you read a ceramic capacitor marking?

Ceramic disc capacitor code / label will normally consist of three numbers followed by a letter. They are very easy to decode to find the value. 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.

Where is the value of a capacitor marked?

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..

Is it OK to use a higher uF capacitor?

Yes, you can replace a capacitor with one of a slightly higher uF, but try to stay as close as possible to the original number and don’t go lower. Replacing a capacitor is sometimes referred to as “recapping a circuit board,” and it’s important to match the new capacitor up to the old one.

What are the markings on a capacitor?

Electronics Components: How to Read Capacitance Values on a Capacitor

Marking Capacitance (pF) Capacitance (ìF)
103 10,000 pF 0.01 ìF
223 22,000 pF 0.022 ìF
473 47,000 pF 0.047 ìF
104 100,000 pF 0.1 ìF

Can I replace a capacitor with a higher UF?

An electric motor start capacitors can be replaced with a micro-farad or UF equal to or up to 20% higher UF than the original capacitor serving the motor.

What is the value of 472 capacitor?

Electronics Components: How to Read Capacitance Values on a Capacitor

Marking Capacitance (pF) Capacitance (ìF)
471 470 pF 0.00047 ìF
102 1,000 pF 0.001 ìF
222 2,200 pF 0.0022 ìF
472 4,700 pF 0.0047 ìF

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 do you find the value of 103 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.

How do I find the value of a SMD capacitor?

How to test a SMD capacitor?

  1. Step1 – Remove your capacitor from the PCB ( it is not possible to test the component without removing it from the board)
  2. Step2 -Put your multimeter to the Mega-ohm range.
  3. Step3 – Now observe the value Of the component,

What happens if you use the wrong size capacitor?

If the wrong run capacitor is installed, the motor will not have an even magnetic field. This will cause the rotor to hesitate at those spots that are uneven. This hesitation will cause the motor to become noisy, increase energy consumption, cause performance to drop, and cause the motor to overheat.

What do the numbers mean on a capacitor marking?

Capacitor Marking. A capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance.

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.

Are there markings on SMD ceramic capacitors?

SMD ceramic capacitor codes: Surface mount capacitors are often very small and do not have the space for markings. During manufacture the capacitors are loaded into a pick and place machine and there is no need for any markings.

How do you read the capacitor tolerance code?

Some capacitors are defined by a three number code followed by a letter. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. The tolerances are indicated as follows. Read B as 0.10 percent. Read C as 0.25 percent.
