Material Notes:
Mylar® Type C films are available in a wide range of generally thinner gauges (typically 10 through 92) that offer excellent electrical properties, combined with superior strength and dimensional stability.Mylar® Type C films offer the ideal combination of tensile strength, dimensional stability, and electrical properties needed for use in capacitors.Mylar® Type C films were developed specifically as a dielectric for use in metallized and film/foil capacitors. Typical capacitor applications include energy storage, frequency discrimination, filtering, coupling, and by-passing.Approvals: UL 94 VTM-2 - for 92 - 500 gauge (0.023 - 0.13mm) and UL Recognition - for 92 - 500 gauge (0.023 - 0.13mm) - HWI=5, HAI=4, CTI=1Information provided by DuPont.
