IEC: International Electrotechnical Commission, iec.org, made up from many national standards organizations. Its various activities were take over by about a half dozen other organizations. 1953 to 1957.ĮIA: Electronic Industries Alliance. RETMA: Radio Electronics Television Manufacturers' Association. The tighter tolerances mostly apply to small C0G capacitors and the looser tolerances to larger Class 2-4 ceramics.įor example, if you see. Once again, don't expect to find all possible combinations of values, dielectrics, and tolerances.

Table 5 shows the EIA tolerance codes for ceramic capacitors. With luck, you might also find the material (C0G, X7R, etc.) and voltage rating. Values below 10 pF may use "R" for a decimal point, 4R7 = 4.7 pF for example.

However, 479 will probably mean 4.7 (47 x 10 -1). Tantalum Capacitor 1 ABBRIVIATION OF TANTALUM CAPACITOR 2 TYPE OF SERIES 3 RATED VOLTAGE 4 CAPACITANCE 5 CAPACITANCE TOLERANCE 6 CASE SIZE Symbol Tolerance() Symbol Tolerance() K ☑0 M ☒0 Case EIA Code Case EIA Code J 1608 C 6032 P 2012 D 7343 A 3216 B 3528 The symbol shows the type of the capacitor. This, like most marking systems, is based on the picofarad, the lowest common denominator of capacitance. On small through-hole ceramics, a two-number-plus-exponent system is often (but not always) used. However, the smaller the part gets, the less information you get until, on the smallest parts there may be nothing at all. If the manufacturer has lots of room (like on big electrolytics) they will usually print everything they can value, voltage rating, temperature rating, series, even country of manufacture. It would be nice if there was more consistency to capacitor markings. Microwave capacitors go down to at least 50 fF, but are called 0.05 pF. "Femto farad " (fF) is used for things like RAM chip storage capacitors, but there are no discrete capacitors in that size range. Nano is rather less common than micro and pico, but it still shows up. Printed on heavy-grade glossy card in A3 size (297x420mm), its easy to read and keeps critical information right where you need it. 1 mF (milli) = 10-3 farad, 1 uF (micro) = 10-6 farad. This handy wall chart is a great quick-reference guide for your workshop or hackerspace. So this is how a capacitor value/code calculator calculates the ceramic capacitor value from the capacitor code, or vice versa.First, let's get our nomenclature straight. The capacitance value will be calculated as follows: Similarly if the capacitor code is 152, the 3 rd digit is 2 so multiplier factor is 100.

To understand how multiplier works, let’s take an example of a capacitor with code ‘104’.Īs 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: If 3 rd digit is 6, it means multiplier factor of 1000000. If 3 rd digit is 5, it means multiplier factor of 100000. If 3 rd digit is 4, it means multiplier factor of 10000. If 3 rd digit is 3, it means multiplier factor of 1000. If 3 rd digit is 2, it means multiplier factor of 100. NSPH series, High Capacitance SMT Film Chip Capacitors. If 3 rd digit is 1, it means multiplier factor of 10. (3-digit capacitance code & corresponding capacitance value) for 0402 case size to 2225 case size. If 3 rd digit is 0, it means multiplier factor of 1. For example if a ceramic capacitor has a code ‘5’ and other has ‘47’, their respective capacitance values are 5 pF and 47 pF.įor 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. If the capacitor code consist only 1 or 2 digits, it is simply their capacitance value in PicoFarads (pF). For electrolytic capacitors, simply capacitance values are written on them.Ĭeramic capacitors encoding consists 1-3 digits.

By using this capacitor value calculator, we can calculate the value of that capacitor, or vice versa. How Capacitor Value/Code Calculator Works?Īs ceramic capacitors have less surface area because of their tiny size, their value is not written in the capacitor, instead an encoded code is written on them. This Capacitor Code Calculator calculates the ceramic capacitor code upon providing the capacitance value of the capacitor in the input field below. This Capacitor Value Calculator calculates the capacitance value of a ceramic capacitor upon providing the capacitor code in the input field below.
