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.

Ceramic capacitor typical voltage rating.

2a is a 100vdc rating according to the eia electronic industries alliance standard. The 104 capacitance indicator has no bearing whatsoe. Different types of ceramic capacitors. 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 with high to very high power or voltage ratings for applications. It could even be 250v. The voltage rating could be 50v it could be 100v. 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.

Mlccs are used instead if capacitance values allow. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. Multi layer ceramic capacitor mlcc. 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.

A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf. Figure 1 graphs the data that i extracted from the murata tool for several different 4 7µf ceramic capacitors. I investigated 4 7µf capacitors of various sizes and voltage ratings.
