Ceramic Capacitor 104 Voltage Rating

The voltage rating always mentioned on it.

Ceramic capacitor 104 voltage rating.

The voltage rating on a capacitor is the maximum amount of voltage that a capacitor can safely be exposed to and can store. 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. Ever wondered about the types of ceramic capacitors available in market and how to select one for your project. The 3 digit code 104 written over ceramic capacitor indicates its value.

Generally smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small. The voltage rating of the ceramic capacitor depends on the size and the capacitance value. The voltage rating could be 50v it could be 100v. 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.

One is their capacitance c farad itself and the other is its voltage v volts rating. 2a is a 100vdc rating according to the eia electronic industries alliance standard. 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. The main thing you need to know about capacitors is that they store x charge at x voltage.

Capacitor is a passive component which can store a charge q. Ceramic caps are really durable mlcc s are often tested at rated to 200 rated voltage for 1000 hours before failure. The 104 capacitance indicator has no bearing whatsoe. The rating is defined during the manufacturing of the capacitor.

It could even be 250v. Remember that capacitors are storage devices. Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain voltage 10v 25v 50v etc.
