With a stripe (either white on black body or black on light body), a "+", a sharp bevel, or some combination. When it comes to polarity identification, tantalum manufacturers are totally fixated on the anode, either At least oneĬompany sometimes uses the letter part of the EIA code, without the exponent, to indicate uF instead of pF (J would be 2.2 uF).

Voltage/value schemes loosely based on the EIA codes, but with modifications and additions. Variations include date codes based on a system of dots, and special Mostly apply to small C0G capacitors and the looser tolerances to larger Class 2-4 ceramics. 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 This, like most marking systems, is based on the picofarad, the lowest commonÄenominator 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

Usually print everything they can value, voltage rating, temperature rating, series, even country of manufacture. If the manufacturer has lots of room (like on big electrolytics) they will It would be nice if there was more consistency to capacitor markings. "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. Size Chart - Footprint Selection chart - TopLine Dummy Component Foot Print Cross Reference.
