Multilayer epoxy coated Monolithic ceramic capacitors in NPO ( COG ) Class 1 and X7R ( Class 2 ), which are now commonly used as they are much smaller compared to the old brown ceramic types. Brands include AVX, TDK, Torch, Hitano, and Vishay.
MLCC NPO ( COG ) class 1 capacitors are temperature stable and suited to RF oscillators and constructing low loss RF filters. X5R/X7R class 2 types are temperature stable and are suitable where moderate capacitance changes are acceptable and suitable for audio and decoupling of power supplies etc. Z5U/Y5V class 3 are for general purpose use and mainly used for power supply decoupling. The 50 volt versions are suitable for up to 10 watts of RF, and the 200 to 250 volt versions should be suitable for up to 100 watts of RF.
Refer to the part description for capacitance, temperature, voltage, and lead spacing.
