What does 103 on a capacitor mean?
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.

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.
What does 101 on a capacitor mean?
100 pF

What do the numbers on my capacitor mean?
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.

What are the numbers on ceramic capacitors?
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 do I identify 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.
How are capacitors 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..
What is the value of capacitor 106?
So, for example, if the digits are ‘106’, this equals a capacitance value of 10μF. The first 2 digits are ’10’ and the multiplier factor is 1,000,000, so the value is 10,000,000pF or 10μF (10pF x 1,000,000= 10,000,000pF= 10μF). Again, for last digit cannot be greater than 6.
What does 104 mean on capacitor?
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.
What is the value of this capacitor 103?

How do I know if a capacitor is bad?
How to tell if a AC Capacitor is Bad! Visual and Multimeter Testing!
How do you check if a capacitor is bad?
Use the multimeter and read the voltage on the capacitor leads. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should be replaced.
How do you identify a capacitor?

What is capacitor code?
Capacitor colour codes are a simple and effective visual way of identifying the capacitance value of a capacitor. Advertisement. There are two common ways to know the capacitive value of a capacitor, by measuring it using a digital multimeter, or by reading the capacitor colour codes printed on it.
What numbers are important on a capacitor?
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
What happens when capacitor goes bad?
A bad capacitor prevents the exterior unit from properly functioning, which hinders the cooling process as a whole. Second, improper voltage delivery to exterior unit components forces the system to work harder as it attempts to perform its job. Additional components often sustain damage due to a faulty capacitor.

What happens when a run capacitor goes bad?
A run capacitor is an energy-saving device that is in the motor circuit at all times. If a run capacitor fails, the motor can display a variety of problems including not starting, overheating, and vibrating. A bad run capacitor deprives the motor of the full voltage it needs to operate correctly.
What does the temperature rating on a capacitor mean?
The Temperature Coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. The temperature coefficient of a capacitor is generally expressed linearly as parts per million per degree centigrade (PPM/oC), or as a percent change over a particular range of temperatures.
Are capacitors affected by temperature?
Capacitance of ceramic capacitors changes by ambient temperature. This change is called capacitance temperature characteristics. This is caused by the material used in ceramic capacitors, and generally occurs on ceramic capacitors of other companies.
