Product Overview
This document outlines the approval specifications for Dersonic CBB28 series film capacitors. These capacitors are designed for electronic equipment, featuring a metallized polypropylene film/foil construction with a wound structure. They offer low loss, small inherent temperature rise, and a negative temperature coefficient of capacitance. The capacitors are encapsulated in flame-retardant epoxy resin powder coating (UL94/V-0) and are RoHS 2.0, Halogen-free, and REACH compliant. Applications include horizontal resonance circuits of large screen monitors, high pulse and high current loading circuits, and electronic ballasts.
