Insulation & Protection Materials for Capacitors
Film and foil capacitors are the most commonly used capacitors in the industry. Their essential differentiator is the dielectric used and its properties. Film capacitors come in capacitance ranges from as small as 5pF to as large as 100uF. A special subcategory are plastic film capacitors, which use polystyrene, poly-
Understanding Capacitor Types and Characteristics | DigiKey
Film capacitors. Film capacitors use a thin plastic film as a dielectric. Conducting plates can be implemented either as foil layers or as two thin layers of metallization, one on each side of the plastic film. The plastic used for the dielectric determines the characteristics of the capacitors. Film capacitors come in many forms:
