Tantalum Capacitor Polarity Markings. Tantalum, OSCO N, and Aluminum Electrolytic capacitors are all polarized (specifically to be used as a bypass capacitor). Tantalum Capacitors AVX is the number one tantalum capacitor supplier with four manufacturing plants worldwide, which provides flexibility and capacity for the demanding electronic industry. Tantalum capacitors can accommodate a variety of environmental conditions such as temperature, humidity, shock, vibration, mechanical and electrical stress, including applied voltage, current, ripple current, transient current and voltage. Wet tantalum capacitors now use the intrinsic capability of a proprietary cathode system to provide high capacitance/voltage characteristics, allowing them to be qualified to DSCC 93026. We have conducted both computerized signal analysis and blind listening tests using various capacitor dielectric types including aluminum, tantalum, silver-mica, ceramic, polyester, polystyrene and polypropylene. Scrap Capacitors & Tantalum Capasitor Scrap Scrap Capacitors shall consist of whole or recovered capacitors must be primarily tantalum capacitor materials. The key factor in distinguishing different types of capacitors is the Dielectric used in its construction. It is almost immune to chemical attack at temperatures below 150 C.
