Ceramic Disc Capacitor Voltage Rating

Ceramic disc capacitors have two to three digits code printed on them.

Ceramic disc capacitor voltage rating.

Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more. The voltage rating could be 50v it could be 100v. 1 kv 1 000 volts. This is the maximum voltage the capacitor is designed to handle.

Typically the markings on a capacitor may give the figures like 22 and 6v. A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. These meet the ul 94 v0 standard. Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc.

Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more. A variety of schemes may be used. Multi layer ceramic capacitor mlcc mlccs are manufactured by accurately mixing finely ground granules of paraelectric and ferroelectric materials and alternatively layering the mix with metal contacts. For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits.

Nov wed 20 2019 8 56 pm. It could even be 250v. How to identify its voltage rating. If a capacitor is marked with 2a474j the capacitance is decoded as described above the two first signs is the voltage rating and can be decoded from the table given below here.

The 104 capacitance indicator has no bearing whatsoe. Say a ceramic capacitor with the code 103 0 01 micro farad. Check the voltage rating. Jan thu 01 1970 1 00 am posts.

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Ceramic disk capacitor voltage rating. When comparing disk capacitors of the same type and manufacturer it s the thickness that gives you an idea of how much voltage they can withstand. 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.

If you break one open and look at the actual ceramic not including the outer coating if it is about the thickness of a credit card or less you re talking perhaps 50 or 100 volts. Slidell la normal means caps that are specified in standards such as eia 198 for ceramic capacitors. For switched mode power supply applications epoxy coated flame retardant capacitors are usually used. 2a is a 100vdc rating according to the eia.

This includes x7r z5u c0g np0 is obsolete and most other tcs you can think of. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.
