Ceramic Capacitor 104 Voltage Rating

Remember that capacitors are storage devices.

Ceramic capacitor 104 voltage rating. It could even be 250v. The voltage rating could be 50v it could be 100v. A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. Codes of polyester film and metallized film capacitor.

The 104 capacitance indicator has no bearing whatsoe. Generally smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small. The main thing you need to know about capacitors is that they store x charge at x voltage. Ceramic capacitors can be classified based on two main parameters.

The voltage rating of the ceramic capacitor depends on the size and the capacitance value. 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. 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 3 digit code 104 written over ceramic capacitor indicates its value.

Ceramic caps are really durable mlcc s are often tested at rated to 200 rated voltage for 1000 hours before failure. The rating is defined during the manufacturing of the capacitor. 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.

One is their capacitance c farad itself and the other is its voltage v volts rating. 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. Meaning they hold a certain size charge 1µf 100µf 1000µf etc at a certain voltage 10v 25v 50v etc.
