Capacitors are generally made with regards to the dielectric used between the plates. Some capacitors look like tubes, small capacitors are often constructed from ceramic materials and then dipped into an epoxy resin to seal them.These ceramic disc capacitors have many general purpose electronic applications, most commonly being load capacitors for crystal oscillators. Package include: 10 x 1uF 63V Electrolytic Capacitor SKU: PGI-00195 Category: Capacitor
