High Voltage Ceramic Capacitor Code

Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time.

High voltage ceramic capacitor code.

Typically the markings on a capacitor may give the figures like 22 and 6v. This indicates a 22µf capacitor with a maximum voltage of 6v. But it is difficult to identify the values in the case of old capacitors. For example 204 20 10 4 200000 pf.

Let us see an example of ceramic or disc capacitor for calculating the color code on it. See below if you suspect your capacitor uses a code for voltage a single letter or one digit and one letter. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. 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.

1 kv 1 000 volts. These colour codes are used from many years for non polarized capacitors like disc and ceramic capacitors. A variety of schemes may be used. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board.

If there is no symbol at all reserve the cap for low voltage circuits only. Npo type capacitors are frequently used for precision timing filtering frequency setting and tuning circuits. Disc capacitors with colour codes. Then by just using numbers and letters as codes.

Disc ceramic capacitor. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5. If a capacitor has 682 code first check the last no here last no is 2. Case size codes are based on the sizes in 0 01s of an inch in english and 0 1 mm in metric.

Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. 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. 472 47 10 2 4700 pf. Hence the value of the capacitor above is 47000 pf 5.

High voltage ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components. Case code 0603 eia english and 1608 iec metric is 063 x 031 in english and 1 6 x 8 mm in metric. Case codes are most often seen with tantalum capacitors. Now the multiplier is 10 2.

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. The tantalum codes can include hight as well. If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code.
