Polycarbonate caps have been used extensively in applications where high precision, wide temp range and high effencies are desired. I do think they are being phased out, however.
Ceramic - Made with various ceramic dielectrics which generally have a trade-off between capacitance per unit size and temperature stability.
Film - These have film dielectrics such as various plastics (polycarbonate, polypropylene, polystyrene, polyester, etc.) and paper (generally obsolete except for oil-filled paper).
Electrolytic - Polarized types. Largest capacitance values. Aluminum is cheapest and most common. Tantalum is more expensive but has better performance.
hello, i'm new here. i have a question regarding capacitors...
is it plausible to connect a capacitor to a twin pronged dart and use that dart as a shock weapon. (i ask only for research for a publication i am working on, hope this is ok)
