Coaxial同軸音頻接口浪涌靜電ESD保護方案及電路保護器件選型

同(tong)(tong)(tong)軸(zhou)音頻接(jie)口（Coaxial）是(shi)(shi)(shi)用(yong)于傳(chuan)(chuan)輸(shu)高頻率(lv)數(shu)字訊號(hao)的(de)(de)75歐姆同(tong)(tong)(tong)軸(zhou)線材作為(wei)搭配標準(zhun)的(de)(de)設備。其(qi)優(you)點是(shi)(shi)(shi)阻抗恒定，傳(chuan)(chuan)輸(shu)頻帶(dai)較(jiao)寬(kuan)， 優(you)質的(de)(de)同(tong)(tong)(tong)軸(zhou)電(dian)(dian)(dian)纜(lan)頻寬(kuan)可達幾(ji)百兆赫。同(tong)(tong)(tong)軸(zhou)數(shu)字傳(chuan)(chuan)輸(shu)線標準(zhun)接(jie)頭采用(yong)BNC頭，其(qi)阻抗是(shi)(shi)(shi)75Ω，與75Ω的(de)(de)同(tong)(tong)(tong)軸(zhou)電(dian)(dian)(dian)纜(lan)配合，可保(bao)證(zheng)阻抗恒 定，確保(bao)信號(hao)傳(chuan)(chuan)輸(shu)正確。既然是(shi)(shi)(shi)數(shu)據信號(hao)的(de)(de)傳(chuan)(chuan)輸(shu)，那么，在(zai)傳(chuan)(chuan)輸(shu)過程中，自然容易(yi)受(shou)到靜電(dian)(dian)(dian)的(de)(de)干擾，影(ying)響信號(hao)的(de)(de)傳(chuan)(chuan)輸(shu)甚至失效。針 對(dui)Coaxial同(tong)(tong)(tong)軸(zhou)音頻接(jie)口浪涌靜電(dian)(dian)(dian)放電(dian)(dian)(dian)問題，電(dian)(dian)(dian)子工程師通常會選用(yong)保(bao)護(hu)器(qi)件(jian)為(wei)其(qi)保(bao)駕(jia)護(hu)航。接(jie)下來(lai)，高品質保(bao)護(hu)器(qi)件(jian)生(sheng)產(chan)廠家及保(bao) 護(hu)方案服務商東沃電(dian)(dian)(dian)子要(yao)
