Capacitor Details

Unlike resistors, 1nj100 capacitor use a wide variety of codes to describe their characteristics. Physically small capacitors are especially difficult to read, due to the limited space available for printing. The information in this article should help you read almost all modern consumer capacitors. Don’t be surprised if your information is printed in a different order than the one described here, or if voltage and tolerance info is missing from your capacitor. For many low-voltage DIY circuits, the only information you need is the capacitance.

Most large capacitors have a capacitance value written on the side. Slight variations are common, so look for the value that most closely matches the units above. You may need to adjust for the following:
Ignore capital letters in the units. For example, “MF” is just a variation on “mf.” (It is definitely not a megafarad, even though this is the official SI abbreviation.)

Don’t get thrown by “fd.” This is just another abbreviation for farad. For example, “mmfd” is the same as “mmf.”
Beware single-letter markings such as “475m,” usually found on smaller capacitors.

Some 1nj100 capacitor new list a tolerance, or the maximum expected range in capacitance compared to its listed value. This isn’t important in all circuits, but you may need to pay attention to this if you require a precise capacitor value. For example, a capacitor labeled “6000uF +50%/-70%” could actually have a capacitance as high as 6000uF + (6000 * 0.5) = 9000uF, or as low as 6000 uF – (6000uF * 0.7) = 1800uF.

If there is no percentage listed, look for a single letter after the capacitance value or on its own line. This may be code for a tolerance value

If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for “Working Voltage”). This is the maximum voltage the capacitor is designed to handle.
1 kV = 1,000 volts.

See below if you suspect your capacitor uses a code for voltage (a single letter or one digit and one letter). If there is no symbol at all, reserve the cap for low-voltage circuits only.

If you are building an AC circuit, look for a capacitor rated specifically for VAC. Do not use a DC capacitor unless you have an in-depth knowledge of how to convert the voltage rating, and how to use that type of capacitor safely in AC applications.

If you see one of these next to a terminal, the capacitor is polarized. Make sure to connect the capacitor’s + end to the positive side of the circuit, or the capacitor could eventually cause a short or even explode. If there is no + or -, you can orient the capacitor either way.
Some capacitors use a colored bar or a ring-shaped depression to show polarity.

Traditionally, this mark designates the – end on an aluminum electrolytic capacitor (which are usually shaped like tin cans). On tantalum electrolytic capacitors (which are very small), this mark designates the + end. (Disregard the bar if it contradicts a + or – sign, or if it is on a non-electrolytic capacitor.)

Older capacitors are less predictable, but almost all modern examples use the EIA standard code when the capacitor is too small to write out the capacitance in full.

If your code starts with exactly two digits followed by a letter (e.g. 44M), the first two digits are the full capacitance code. Skip down to finding units.
If one of the first two characters is a letter, skip down to letter systems.
If the first three characters are all numbers, continue to the next step.

The three-digit capacitance code works as follows:
If the third digit is 0 through 6, add that many zeroes to the end of the number. (For example, 453 → 45 x 103 → 45,000.)

The smallest capacitors (made from ceramic, film, or tantalum) use units of picofarads (pF), equal to 10-12 farads. Larger capacitors (the cylindrical aluminum electrolyte type or the double-layer type) use units of microfarads (uF or µF), equal to 10-6 farads.

A 1nj100 capacitor best may overrule this by adding a unit after it (p for picofarad, n for nanofarad, or u for microfarad). However, if there is only one letter after the code, this is usually the tolerance code, not the unit. (P and N are uncommon tolerance codes, but they do exist.)

If your code includes a letter as one of the first two characters, there are three possibilities:
If the letter is an R, replace it with a decimal point to get the capacitance in pF. For example, 4R1 means a capacitance of 4.1pF.

If the letter is p, n, or u, this tells you the units (pico-, nano-, or microfarad). Replace this letter with a decimal point. For example, n61 means 0.61 nF, and 5u2 means 5.2 uF. A code like “1A253” is actually two codes. 1A tells you the voltage, and 253 tells you the capacitance as described above
