自恢復(fù)保險(xiǎn)絲原理 自恢復(fù)保險(xiǎn)絲(以下簡稱保險(xiǎn)絲)由聚合物樹脂基體及分布在里面的導(dǎo)電粒子組成，在正常情況下，導(dǎo)電粒子在樹脂基體中構(gòu)成鏈狀導(dǎo)電通路，保險(xiǎn)絲表現(xiàn)為低阻抗（a）。電路中有過電流發(fā)生時，流經(jīng)保險(xiǎn)絲的大電流產(chǎn)生的熱量使聚合物樹脂基體體積膨脹，切斷了導(dǎo)電粒子形成的鏈狀導(dǎo)電通路，導(dǎo)致保險(xiǎn)絲的阻抗迅速升高，從而起到對電路的過流保護(hù)作用（b）。故障排除后，樹脂重新冷卻結(jié)晶，體積收縮，導(dǎo)電粒子重新形成導(dǎo)電通路，保險(xiǎn)絲恢復(fù)為低阻抗。 SMD0805P010TF SMD0805P020TF SMD0805P035TF SMD0805P050TF SMD0805P075TF SMD0805P100TF SMD1206P012TF SMD1206P016TF SMD1206P020TF/24 SMD1206P025TF SMD1206P035TF/16 SMD1206P050TF SMD1206P050TF/15 SMD1206P075TF SMD1206P100TF SMD1206P110TF SMD1206P150TF SMD1026P200TF SMD1210P005TF SMD1210P010TF SMD1210P020TF SMD1210P035TF SMD1210P050TF SMD1210P075TF SMD1210P110TF SMD1210P150TF SMD1812P010TF SMD1812P014TF SMD1812P020TF SMD1812P050TF SMD1812P075TF SMD1812P110TF 是一家專業(yè)保險(xiǎn)絲及世界zm電子元件的代理商。公司積{jz}力于為客戶提供品質(zhì)優(yōu)良的過流過壓保護(hù)元器件，使電路免受破壞 ，提供高質(zhì)量的電路保護(hù)解決方案是我們?yōu)榭蛻舴?wù)的宗旨。
