A ceramic capacitor marked 104 has a value plus as much as 80 to 20 tolerance of 100000pf or 100nf or 0 1uf.
Ceramic disc capacitor voltage rating.
Typically the markings on a capacitor may give the figures like 22 and 6v.
Ceramic disc capacitors have two to three digits code printed on them.
For switched mode power supply applications epoxy coated flame retardant capacitors are usually used.
A variety of schemes may be used.
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.
The 104 capacitance indicator has no bearing whatsoe.
Slidell la normal means caps that are specified in standards such as eia 198 for ceramic capacitors.
Check the voltage rating.
Nov wed 20 2019 8 56 pm.
The voltage rating could be 50v it could be 100v.
These meet the ul 94 v0 standard.
2a is a 100vdc rating according to the eia.
This includes x7r z5u c0g np0 is obsolete and most other tcs you can think of.
Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise.
It could even be 250v.
This indicates a 22µf capacitor with a maximum voltage of 6v.
I intend to use the capacitor in a rf receiver circuit 20mhz where the maximum voltage is 12 v.
Ceramic disk capacitor voltage rating.
Searching for a 0 01 micro farad capacitor in mouser the voltage rating is indicated as 1kv dc.
Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates.
1 kv 1 000 volts.
Ceramic disc capacitors come in many versions.
If there is room on the body of the capacitor the manufacturer usually lists voltage as a number followed by a v vdc vdcw or wv for working voltage.
Jan thu 01 1970 1 00 am posts.
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.
How to identify its voltage rating.
For basic general applications the brown ones are usually utilised for decoupling in low voltage circuits.
Say a ceramic capacitor with the code 103 0 01 micro farad.
When comparing disk capacitors of the same type and manufacturer it s the thickness that gives you an idea of how much voltage they can withstand.
This is the maximum voltage the capacitor is designed to handle.
