DuPont Teijin Films Mylar® C Polyester Film, 92 Gauge
Categories:	Polymer; Film; Thermoplastic; Polyester, TP; Polyester Film
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=1 Information provided by DuPont.
