薄膜鉑電阻元件

一、         概述

      CRZ系列薄膜鉑熱電阻元件是把金屬鉑研制成粉漿，采用先進的激光噴濺薄膜技術及光刻法和干燥蝕刻法把附著在陶瓷基片上形成膜，引線經(jīng)過激光調(diào)阻制成，*自動的生產(chǎn)程序保證了產(chǎn)品*符合IEC標準。

二、         技術特點

1．              薄膜鉑熱電阻元件用陶瓷和鉑制成，因而在高溫下能夠保持優(yōu)良的穩(wěn)定性，適合在-50～400℃的溫度下使用。

2．              鉑薄膜通過激光噴濺在陶瓷表層，因而它具有良好的防震和防沖擊性能。

3．              薄膜表面蓋以陶瓷，因而元件能夠承受高壓，并具有良好的絕緣性。

4．              引線材料為鎳鍍金和純鈀兩種。
