Ceramic Disc Capacitor Voltage Rating

It could even be 250v.

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. Nov wed 20 2019 8 56 pm. 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. 2a is a 100vdc rating according to the eia.

Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc. A variety of schemes may be used. Ceramic disc capacitors have two to three digits code printed on them. 1 kv 1 000 volts.

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. 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. For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits.

A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. The 104 capacitance indicator has no bearing whatsoe. 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. 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.

This is the maximum voltage the capacitor is designed to handle. This indicates a 22µf capacitor with a maximum voltage of 6v. 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. Typically the markings on a capacitor may give the figures like 22 and 6v.

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. The voltage rating could be 50v it could be 100v. Ceramic disk capacitor voltage rating.

For switched mode power supply applications epoxy coated flame retardant capacitors are usually used. Jan thu 01 1970 1 00 am posts. This includes x7r z5u c0g np0 is obsolete and most other tcs you can think of. These meet the ul 94 v0 standard.

Ceramic disc capacitors come in many versions. I intend to use the capacitor in a rf receiver circuit 20mhz where the maximum voltage is 12 v.
