Method of finding the value meaning of codes of capacitor. When the ceramic capacitor are layered multiple times it becomes mlcc. Ceramic disc capacitors are available at mouser electronics from industry leading manufacturers. The two most common types are multi layer ceramic capacitors and ceramic disc capacitors.

Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance. Taking a look at this site today has enlightened me to not only letters on the caps but voltage codes as well. The first two significant digits represent the first two digits of the actual value which is 47. An american company in the midst of the apollo program launched in 1961 pioneered the stacking of multiple discs to create a monolithic block.

I have always been unaware of the markings on a disc ceramic capacitor such as j m and other symbols.
