Film capacitors are insulated with polyester, polycarbonate, polypropylene, polystyrene, or other dielectric materials. Polyester film capacitors offer a high dielectric constant and high dielectric strength with volumetric. Metallized polyester film provides excellent self-healing properties, allowing capacitors to withstand high-pulsed voltages without breaking the dielectric. Polycarbonate film capacitors offer very low temperature dependency, wide operating temperature range, good long-term stability and low losses. Polypropylene film capacitors provide very low losses, low dielectric absorption, and high dielectric strength. They also offer very high insulation resistance and negative temperature coefficient. Polystyrene film capacitors provide extremely low losses, low dielectric absorption, good long-term stability, very high insulation resistance and a small negative temperature coefficient. |
Products & Services Related to Film Capacitors
Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not.
Capacitors
Capacitors are electronic components used for storing charge and energy. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric.
Chip Capacitors
Chip capacitors or surface mount capacitors do not have leads.
High Voltage Capacitors
High voltage capacitors are used for storing charge and energy in high voltage applications.
Power Capacitors
Power capacitors are used in electrical distribution systems to provide a static source of leading reactive power.
Tantalum Capacitors
Tantalum capacitors are used in smaller electronic devices including portable telephones, pagers, personal computers, and automotive electronics.
Ultracapacitors
Ultracapacitors store charges (energy) by physically separating positive and negative charges (unlike batteries which do so chemically). Very high power densities can be achieved by this method.
