Study on the Influence Factors of Leakage Current of Tantalum Wires for Capacitors

研究了钽丝的纯度、漏电流检测条件对钽丝漏电流的影响。结果表明,钽丝中化学杂质的含量对钽丝漏电流的影响尤为明显,而合适配比的掺杂剂和掺杂量可以显著降低钽丝的漏电流;钽丝的阳极氧化条件也是影响漏电流的重要因素。可以通过控制钽丝的纯度、优化阳极氧化形成条件,获得稳定、可靠的钽丝漏电流。

The effects of the tantalum wire purity and leakage current test conditions analysis on the tantalum wire leakage current were studied.Results showed that the appropriate content of doping agent and the suitable ratio could significantly reduce the leakage current of tantalum wire.The anodic oxidation condition of tantalum wire was also an important factor affecting the leakage current.By controlling the purity of tantalum wire and optimizing anodizing conditions,the stable and reliable tantalum wire leakage current could be obtained.
