What is the code for a ceramic capacitor?

Encoding for Ceramic Capacitors 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 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.

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.

What is the 3 digit capacitor code in PF?

For 3 digit’s capacitor code, the first two digits are the capacitance value in pF and the third digit is a multiplier factor of first two digits to calculate the final capacitance value of the capacitor. The 3rd digit ranges between 0-6.

Engineers usually do not require calculators because the code is so simple. Here is another example, code 104 is 10 followed by four zeros, hence 10 0000 pF. As you can see, it is so easy that you can do this in your head. EXAMPLES: If a capacitor is marked 103J, its value is 10,000 pF ±5 %.

How to read the capacitor code UF or PF?

The designators uF or pF will not appear due to the small size of the capacitor body. Read two digit numbers as being in picoFarads (pF). For example, 47 would be read as 47 pF. Read three digit numbers as a base capacitance value in picoFarads and a multiplier. The first two digits will indicate the base capacitor value in picoFarads.

What is the code for a surface mount capacitor?

Often the value may be given in picofarads. Sometimes figures such as 10n will be seen and this indicates a 10nF capacitor. Similarly n51 indicates a 0.51nF, or 510 pF capacitor, etc . . SMD ceramic capacitor codes: Surface mount capacitors are often very small and do not have the space for markings.

What’s the difference between µF, PF and nF capacitor?

The capacitor conversion chart below reveals the equivalents between µF, nF and pF in an easy to use table format. Often when buying from an electronic components distributor or electronic components store, the markings of specifications may use different notations and it may be necessary to convert them.
