Ceramic Disc Capacitor 104 Voltage Rating

This is the maximum voltage the capacitor is designed to handle.

Ceramic disc capacitor 104 voltage rating.

For switched mode power supply applications epoxy coated flame retardant capacitors are usually used. Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc. You should not use the capacitor with voltages that exceed this value. 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.

Ceramic disc capacitors come in many versions. This indicates a 22µf capacitor with a maximum voltage of 6v. 2a is a 100vdc rating according to the eia electronic industries alliance standard. 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.

Check the voltage rating. Typically the markings on a capacitor may give the figures like 22 and 6v. 1 kv 1 000 volts. Codes of polyester film and metallized film capacitor.

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. The 3 digit capacitor code 104 stands for 100 nf in words. A variety of schemes may be used. 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.

These meet the ul 94 v0 standard. For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits. I intend to use the capacitor in a rf receiver circuit 20mhz where the maximum voltage is 12 v. This is a simple online calculator for color band resistor marking inductor color band marking ceramic or tantalum capacitor 3 digit marking and smd resistor 3 digit 4 digit 10 5 2 and eia 96 e96 1 tolerance code marking.

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. This indicates the working voltage really the maximum dielectric breakdown voltage of the capacitor. 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. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.

Say a ceramic capacitor with the code 103 0 01 micro farad.
