Tantalum Wire

Description

Tantalum wire is commonly used as the lead wires on tantalum capacitors. It was the first material used for filaments in light bulbs. This tantalum product is also used in the electronics industry in the manufacture of rectifiers and capacitors. Other applications include medical devices, chemical processing, and lighting applications. As our company can supply tantalum wire with a premium surface finish, it has superior performance in such applications. According to the condition and specification, we can produce all types and the smallest diameter reaching Φ0.1 mm.
