The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code.

Ceramic disc capacitors are available at mouser electronics from industry leading manufacturers. Mouser is an authorized distributor for many ceramic disc capacitor manufacturers including avx kemet murata tdk vishay more.Ī ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectricit is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodesthe composition of the ceramic material defines the electrical behavior and therefore applications. A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. Unclassified unlimited release unclassified unlimited release 3ddr. Hence the value of the capacitor above is 47000 pf 5. In circuits where it is vital to keep a voltage source stable there is usually a large electrolytic capacitor in parallel with a ceramic disc capacitor. Please view our large selection of ceramic disc capacitors below.Ĭeramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance. Ceramic disc capacitors have a capacitance value about10pf to 100mf with a wide variety of voltage ratings between 16v to 15 kv and more. The top of a blown capacitor will be slightly bent outwards in a convex shape rather than flat or slightly indented inwards like a working capacitor. Ceramic disc capacitors are made by coating a ceramic disc with silver contacts on both sides as shown above illustrates. A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. A ceramic capacitor leakage in electronic board can pull down the voltage and cause a lot of intermittent problem to the equipment.Ĭeramic disc capacitors are ideal for higher frequencies but are not good to do bulk filtering because ceramic disc capacitors get to big in size for higher values of capacitance. A busted capacitor can be obviously broken leaking brownish fluid corroded or with the leads severed but sometimes its subtle.
