Ceramic Capacitor 104 Voltage Rating

2a is a 100vdc rating according to the eia electronic industries alliance standard.

Ceramic capacitor 104 voltage rating.

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. One is their capacitance c farad itself and the other is its voltage v volts rating. It could even be 250v. Generally smaller ceramic capacitance design for low voltage devices and the voltage rating can be designed up to 15kv for small.

The 3 digit code 104 written over ceramic capacitor indicates its value. The main thing you need to know about capacitors is that they store x charge at x voltage. 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.

A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. Capacitor is a passive component which can store a charge q. 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 could be 50v it could be 100v.

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 of the ceramic capacitor depends on the size and the capacitance value. 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 104 capacitance indicator has no bearing whatsoe. The voltage rating always mentioned on it. Ceramic capacitors can be classified based on two main parameters.
