How To Read A Ceramic Capacitor With Numeric Coding

Multiplier table ceramic number multiply by additional of zeros 0 none 0 1 10 1 2 100 2 3 1 000 3 4 10 000 4 5 100 000 5 6 1 000 000 6 common temperature coefficient codes ceramic code tolerance c 0 25pf j 5 k 10 m.

How to read a ceramic capacitor with numeric coding.

For example n61 means 0 61 nf and 5u2 means 5 2 uf. If the letter is an r replace it with a decimal point to get the capacitance in pf. If abc is 104 then the digit 104 means 10 104pf 100000pf 100nf 0 1uf. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

If the letter is p n or u this tells you the units pico nano or microfarad. For example 101 represents 100 pf. 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. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.

For small values the letter r is used to denote a decimal point e g. For example your capasitor says 103 this means that the first two digits bone 10 remain as they are bone is 10 the third indicates the number of 0 you have to put after the first two digits bone 10 000 10000 pf 10000 have peak bone farads of capacity you always give in picofarads then if you want you can go to nano farads bone 10 000 nf 10 nf. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. Method of finding the value meaning of codes of capacitor.

If a ceramic capacitor has three digits abc then the value would be ab 10 c pico farad. Ceramic capacitor codes how to read a ceramic capacitor with numeric coding. For example 4r1 means a capacitance of 4 1pf. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to.

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. 0r5 is 0 5 1r0 is 1 0 and 2r2 is 2 2 etc. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. Replace this letter with a decimal point.
