Ihold = Hold Current:maximum current device will sustain for 4 hours without tripping in 25°C still air.
ItRip = Trip Current:minimum current at which the device will trip in 25°C still air.
V-max = Maximum voltage device can withstand without damage at rated current(I-max).
I-max = Maximum fault current device can withstand without damage at rated voltage(V-max).
原為陸海股份有限公司之電子事業,1997年創立於美國加州Fremont,致力於PPTC(高分子正溫度係數)產品的研發與製造;自2000年 遷回台灣後即為美國上市公司設計代工多年;2003年設立大陸工廠拓展大陸市場,經多年努力,在業界享有盛名。
我們擁有領先的技術優勢,工廠並符合ISO規範,所產製之自恢復式保險絲先後取得UL、TUV等安規認證且為業內最早採無鉛製程工廠之 一,更超越ROHS規範暨獲SONY的GP認定。
我們提供客戶創新的電路保護,以確保現今高精密電子產品中的安全性及可靠度。
PPTC(Polymeric Positive Temperature Coefficient),即高分子聚合物正係數溫度元件。又稱可復式保險絲(Resettable Fuse)或聚合物保險絲(Polyfuse),
PPTC核心由高分子材料和導電顆粒製成。兩端以鎳製成電極。外部包以樹脂或塑料薄膜。
在低溫時,聚合物結晶間的導電粒子構成三維網絡,呈導通狀態。當電流過大,致使溫度升高時,體積膨脹,聚合物由結晶態轉為非結晶態,使導電粒子的連繫網絡斷裂,因而不導通或絕緣。當溫度降低,且不再有大電流後,待一小段時間恢復結晶狀態,又可導通。
