Ceramic Capacitor Typical Voltage Rating

Ceramic disc capacitors are usually through hole components and are falling out of favor due to their size.

Ceramic capacitor typical voltage rating.

The typical style for ceramic capacitors beneath the disc at that time called condensers in radio applications at the time after the war from the 1950s through the 1970s was a ceramic tube covered with tin or silver on both the inside and outside surface. It could even be 250v. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Ceramic disc capacitors have a capacitance value of about10pf to 100μf with a wide variety of voltage ratings between 16v to 15 kv and more.

Figure 1 graphs the data that i extracted from the murata tool for several different 4 7µf ceramic capacitors. The voltage rating could be 50v it could be 100v. Ceramic disc capacitors have a capacitance value of 10pf to 100μf with a wide variety of voltage ratings between 16 volts to 15 kv and more. Different types of ceramic capacitors.

Ceramic capacitors with high to very high power or voltage ratings for applications. A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. 2a is a 100vdc rating according to the eia electronic industries alliance standard. 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.

Codes of polyester film and metallized film capacitor. I investigated 4 7µf capacitors of various sizes and voltage ratings. I looked at both x5r and x7r types in package sizes from 0603 to 1812 and with voltage ratings from 6 3v dc to 25v dc.
