Ceramic Capacitor 104 Voltage Rating

Ever wondered about the types of ceramic capacitors available in market and how to select one for your project.

Ceramic capacitor 104 voltage rating.

It could even be 250v. The rating is defined during the manufacturing of the capacitor. The 104 capacitance indicator has no bearing whatsoe. 2a is a 100vdc rating according to the eia electronic industries alliance standard.

Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain voltage 10v 25v 50v etc. Capacitor is a passive component which can store a charge q. 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. Ceramic capacitors can be classified based on two main parameters.

The 3 digit code 104 written over ceramic capacitor indicates its value. A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store x charge at x voltage.

The voltage rating always mentioned on it. Codes of polyester film and metallized film capacitor. Ceramic caps are really durable mlcc s are often tested at rated to 200 rated voltage for 1000 hours before failure. 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 could be 50v it could be 100v. One is their capacitance c farad itself and the other is its voltage v volts rating. Generally smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small.
