The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads.
Ceramic disc capacitor vs electrolytic.
Class 1 capacitors are more accurate and stable over a larger range of temperatures while class 2 capacitors offer more volumetric efficiency more capacitance per unit volume.
There are two main types of ceramic capacitors.

Bias voltage is identical save for the lower voltage one having its graph truncated at its rated voltage.
One of the most common passive component questions we hear is what are the differences between the wide varieties of capacitors when your schematic calls for a capacitor you have many choices.
A metallic coating being applied to an extremely thin polymer film to create the conducting electrodes of the capacitor.
Electrolytic ceramic silver mica mylar monolithic tantalum glass or supercapacitors just to name a few.
Tantalum ceramic capacitors.
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.
In fact many ceramic capacitors i suspect are the exact same part but with different part numbers the same 4 7µf capacitor being sold as both a 35v and 50v capacitor under different labels.
Class 1 and class 2.
When it comes to bypassing a resistor with a parallel capacitor does it make a difference for af or for rf whether the capacitor is an electrolytic or a ceramic disk capacitor.
In general ceramic capacitors are somewhat non linear in their frequency and voltage responses compared to film.
Film capacitor typically denotes polyester or polymer film as the dielectric as another answer points out metallized film capacitors are the same thing.
The ceramic capacitor uses a thin ceramic layer as the dielectric medium whereas the electrolytic capacitor uses an ionic liquid as one of the sheets of the capacitor.
Different types of ceramic capacitors.
By robert cong what s the difference between capacitors.
In this post we compare tantalum capacitor vs ceramic the differences between and benefits of the two.
Tantalum capacitors are a subtype of electrolytic capacitors that use tantalum metal for the anode.
What is an electrolytic capacitor.
Ceramic capacitors and electrolytic capacitors are two main types of capacitors that are widely used in electrical and electronic components.
An electrolytic capacitor is a type of capacitor that uses an electrolyte in order to increase its capacitance.
Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or µf equal to 10 6 farads.
