High-Performance CBB62 Series Metallized Polypropylene Film AC Capacitors: Reliable Solutions for AC Applications

Construction and Materials

Metallized Polypropylene Structure: The capacitors are built using a metallized polypropylene film, a material chosen for its excellent electrical properties. Polypropylene offers high insulation resistance and low dielectric losses, making it ideal for AC applications where stable capacitance and minimal energy dissipation are crucial.

Self-Healing Property: One of the standout features of these capacitors is their good self-healing property. This characteristic allows the capacitor to automatically repair minor defects in the dielectric layer, which can occur due to transient voltage spikes or overvoltage conditions. This self-healing capability significantly enhances the operational reliability and longevity of the capacitor in challenging electrical environments.

Long-Term Stability: The CBB62 capacitors are designed to maintain stable capacitance values over extended periods of operation under load. This long-term stability ensures consistent performance, which is essential for maintaining the accuracy and efficiency of electronic devices over their operational lifespan.

Safety and Reliability

Flame Retardant Epoxy Resin Coating (UL94/V-0): To ensure safety and compliance with stringent safety standards, these capacitors are coated with flame retardant epoxy resin. The UL94/V-0 rating indicates that the resin meets the highest standards of flame retardancy, making the capacitors suitable for applications where fire safety is a critical concern. This coating also provides mechanical protection to the capacitor elements, enhancing their durability and resistance to environmental factors.

Applications

The CBB62 series capacitors find widespread use in various electronic and electrical applications:

• Capacitive Dividers: They are essential components in capacitive voltage dividers used for measuring high AC voltages accurately.

• Energy Meters: These capacitors play a crucial role in energy meters by ensuring accurate voltage measurement and power calculation.

• LED Drivers: In LED driver circuits, capacitors help stabilize voltage and filter out noise, contributing to the reliable operation and longevity of LED lighting systems.

• Power Supplies: They are also used in power supply circuits to improve power factor correction (PFC) and reduce harmonic distortion.
