Ceramic Disc Capacitor Voltage Rating

Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.

Ceramic disc capacitor voltage rating. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. I intend to use the capacitor in a rf receiver circuit 20mhz where the maximum voltage is 12 v. These meet the ul 94 v0 standard. 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.

This includes x7r z5u c0g np0 is obsolete and most other tcs you can think of. Typically the markings on a capacitor may give the figures like 22 and 6v. Check the voltage rating. Nov wed 20 2019 8 56 pm.

The 104 capacitance indicator has no bearing whatsoe. The voltage rating could be 50v it could be 100v. 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. How to identify its voltage rating.

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. 2a is a 100vdc rating according to the eia. It could even be 250v. This is the maximum voltage the capacitor is designed to handle.

A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. 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. Jan thu 01 1970 1 00 am posts.

This indicates a 22µf capacitor with a maximum voltage of 6v. 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. Ceramic disk capacitor voltage rating. Say a ceramic capacitor with the code 103 0 01 micro farad.

Slidell la normal means caps that are specified in standards such as eia 198 for ceramic capacitors. Ceramic disc capacitors come in many versions. A variety of schemes may be used. 1 kv 1 000 volts.

For switched mode power supply applications epoxy coated flame retardant capacitors are usually used. Ceramic disc capacitors have two to three digits code printed on them.
