High Voltage Ceramic Capacitor Code

Case code 0603 eia english and 1608 iec metric is 063 x 031 in english and 1 6 x 8 mm in metric.

High voltage ceramic capacitor code.

A variety of schemes may be used. These are physically much larger than those used on pcbs and have specialized terminals for safe connection to a high voltage supply. Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board.

See below if you suspect your capacitor uses a code for voltage a single letter or one digit and one letter. These colour codes are used from many years for non polarized capacitors like disc and ceramic capacitors. 472 47 10 2 4700 pf. Disc ceramic capacitor.

The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. This is the maximum voltage the capacitor is designed to handle. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. Hence the value of the capacitor above is 47000 pf 5.

330 33 10 0 33 pf 10 0 1 here is a table of mostly used codes of ceramic capacitor and their unit conversion in micro nano and picofarad. This indicates a 22µf capacitor with a maximum voltage of 6v. Let us see an example of ceramic or disc capacitor for calculating the color code on it. Typically the markings on a capacitor may give the figures like 22 and 6v.

Case codes are most often seen with tantalum capacitors. Disc capacitors with colour codes. Now the multiplier is 10 2. Then by just using numbers and letters as codes.

High voltage ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components. If there is no symbol at all reserve the cap for low voltage circuits only. The tantalum codes can include hight as well. For example 204 20 10 4 200000 pf.

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 a capacitor has 682 code first check the last no here last no is 2. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. 1 kv 1 000 volts.

Case size codes are based on the sizes in 0 01s of an inch in english and 0 1 mm in metric. Power ceramic capacitors can be made to withstand voltages in the range of 2kv up to 100 kv with a power specified at much higher than 200 volt amperes. But it is difficult to identify the values in the case of old capacitors.
