Ceramic Disc Capacitor 104 Voltage Rating

A variety of schemes may be used.

Ceramic disc capacitor 104 voltage rating.

How to identify its voltage rating. For switched mode power supply applications epoxy coated flame retardant capacitors are usually used. 1 kv 1 000 volts. 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.

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. For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits. Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.

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. Codes of polyester film and metallized film capacitor. One hundred nanofarads capacitance. The 3 digit capacitor code 104 stands for 100 nf in words.

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. Say a ceramic capacitor with the code 103 0 01 micro farad. 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. I intend to use the capacitor in a rf receiver circuit 20mhz where the maximum voltage is 12 v.

You should not use the capacitor with voltages that exceed this value. 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. This indicates the working voltage really the maximum dielectric breakdown voltage of the capacitor.

Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc. Ceramic disc capacitors come in many versions. 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. These meet the ul 94 v0 standard.

This indicates a 22µf capacitor with a maximum voltage of 6v.
