High Voltage Ceramic Capacitor Code
The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.
High voltage ceramic capacitor code. 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. A variety of schemes may be used. But it is difficult to identify the values in the case of old capacitors. Case code 0603 eia english and 1608 iec metric is 063 x 031 in english and 1 6 x 8 mm in metric.
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. If there is no symbol at all reserve the cap for low voltage circuits only. This indicates a 22µf capacitor with a maximum voltage of 6v. These are physically much larger than those used on pcbs and have specialized terminals for safe connection to a high voltage supply.
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. Now the multiplier is 10 2. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.
Then by just using numbers and letters as codes. 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. 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. For example 204 20 10 4 200000 pf. 472 47 10 2 4700 pf. Case size codes are based on the sizes in 0 01s of an inch in english and 0 1 mm in metric.
Disc ceramic capacitor. Typically the markings on a capacitor may give the figures like 22 and 6v. This is the maximum voltage the capacitor is designed to handle. High voltage ceramic capacitors manufactured by vishay a global leader for semiconductors and passive electronic components.
1 kv 1 000 volts. Case codes are most often seen with tantalum capacitors. Npo type capacitors are frequently used for precision timing filtering frequency setting and tuning circuits. Has a very low dissipation factor and are very stable over wide variations in temperature frequency voltage and time.
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. Let us see an example of ceramic or disc capacitor for calculating the color code on it. These colour codes are used from many years for non polarized capacitors like disc and ceramic capacitors.
