Reliable Performance and Safety: Introducing the CBB28 Series High-Voltage Metallized Polypropylene Film/Foil Capacitors

The CBB28 series of high-voltage metallized polypropylene film/foil capacitors represents a robust solution tailored for demanding applications where reliability and performance are paramount. These capacitors are characterized by their advanced construction, low loss properties, and adherence to stringent safety standards, making them suitable for a wide range of electronic and electrical circuits.

Construction and Design Features

Metallized Polypropylene Film/Foil, Wound Construction: The capacitors are crafted using a combination of metallized polypropylene film and foil in a wound configuration. This construction method ensures high reliability and performance consistency across varying electrical conditions. The use of metallized polypropylene film and foil enhances the capacitor's ability to handle high voltages and current surges effectively.

Low Loss and Small Inherent Temperature Rise: Designed for efficiency, these capacitors exhibit low dielectric losses and minimal inherent temperature rise during operation. This feature is critical in applications where maintaining stable capacitance values and minimizing energy dissipation are essential for long-term performance and reliability.

Negative Temperature Coefficient of Capacitance: The capacitors feature a negative temperature coefficient of capacitance, meaning their capacitance decreases with increasing temperature. This characteristic helps in maintaining stable electrical characteristics over a wide temperature range, ensuring consistent performance in various environmental conditions.

Flame Retardant Epoxy Resin Powder Coating (UL94/V-0): To meet stringent safety requirements, the capacitors are coated with flame retardant epoxy resin powder. This coating not only provides excellent protection against fire hazards but also enhances the capacitors' mechanical durability and resistance to environmental factors, ensuring prolonged operational reliability.
