Capacitance and Voltage Ratings: Tables detail capacitance values and permissible current ratings across various dimensions and voltage levels, from 250V to 1000V.

Dielectric Properties: The document discusses dielectric films like polycarbonate, polyphenylene sulfide (PPS), polyester (PET, PEN), and polypropylene, highlighting their unique properties and applications.

Conclusion: The PHM 912 series represents a significant advancement in capacitor technology, offering compact size, high reliability, and superior performance in demanding environments.

Introduction: An overview of various dielectric materials used in capacitors, highlighting their properties, applications, and performance characteristics.

Dielectric Materials:

Polyester (P.E.T. and P.E.N.): High dielectric constant, good electrical performance, self-healing properties. P.E.N. is ideal for surface-mounted capacitors due to a higher melting point.
Polypropylene (P.P.): Low dielectric losses, high insulation resistance, linear temperature coefficient, limited to 110°C.
Polystyrene (P.S.): Low dielectric losses, excellent stability, suitable for precision capacitors and filter applications.
Reconstituted Mica: Used in high-voltage capacitors, stable across wide temperature ranges, enhanced with solid resins.
Teflon® (P.T.F.E.): Maintains properties from cryogenic to 200°C, low dielectric absorption, ideal for high-temperature applications.

Capacitor Technologies:

Metallized Film Capacitors: Thin metal layer for self-healing, smaller size, suitable for peak or effective current requirements.
Film-Foil Capacitors: Recommended for high current and power applications, reduced series resistance, larger volume, no self-healing.

Performance Characteristics:

Temperature Dependence: Performance varies with temperature, influenced by dielectric type, with figures illustrating operating ranges and changes in electrical characteristics.
Frequency Dependence: Affected by resistive and inductive components, impacting performance at different frequencies. ESR and impedance are key factors.

Conclusion: The document provides detailed insights into the properties and applications of various dielectric materials and capacitor technologies, emphasizing their suitability for different electronic applications.
