Ceramic Disc Capacitor 104 Voltage Rating

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.

Ceramic disc capacitor 104 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. 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. A variety of schemes may be used. Codes of polyester film and metallized film capacitor.

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. This is the maximum voltage the capacitor is designed to handle. For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits. 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.

For those that have it the voltage is marked directly such as 35 or 35v sometimes the letters wv are used after the voltage rating. 2a is a 100vdc rating according to the eia electronic industries alliance standard. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. 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. Typically the markings on a capacitor may give the figures like 22 and 6v. This indicates a 22µf capacitor with a maximum voltage of 6v. Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc.

One hundred nanofarads capacitance. 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 indicates the working voltage really the maximum dielectric breakdown voltage of the capacitor. The 3 digit capacitor code 104 stands for 100 nf in words.

These meet the ul 94 v0 standard. How to identify its voltage rating. 1 kv 1 000 volts. Check the voltage rating.

For switched mode power supply applications epoxy coated flame retardant capacitors are usually used.
