Ceramic Capacitor 104 Voltage Rating

The voltage rating of the ceramic capacitor depends on the size and the capacitance value.

Ceramic capacitor 104 voltage rating.

Generally smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small. Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain voltage 10v 25v 50v etc. The voltage rating could be 50v it could be 100v. Remember that capacitors are storage devices.

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. It could even be 250v. The first two digits 10 of this code are first two digits of capacitor value and third digit 4 gives the number of zeroes to be added so as to get capacitor value in pico. Codes of polyester film and metallized film capacitor.

Capacitor is a passive component which can store a charge q. The 3 digit code 104 written over ceramic capacitor indicates its value. The rating is defined during the manufacturing of the capacitor. 2a is a 100vdc rating according to the eia electronic industries alliance standard.

Ever wondered about the types of ceramic capacitors available in market and how to select one for your project. A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. Ceramic caps are really durable mlcc s are often tested at rated to 200 rated voltage for 1000 hours before failure. Ceramic capacitors can be classified based on two main parameters.

That being said i often find that higher voltage mlcc s can actually be cheaper than the lower voltage for a given capacitance due to higher industry volume for the higher voltage ratings. The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. The voltage rating always mentioned on it.
