貼片壓敏電阻

所謂貼片壓敏電阻，是一種過靜電保護的ESD保護元器件，響應時間ns級，比TVS二極管慢，比陶瓷氣體放電管快，主要應用于主板上的I/O端口（RS232，USB，PS2，VGA，音頻）、筆記本電腦、機頂盒、MP3播放器、DVD播放器、以及對接系統(tǒng)等。貼片壓敏電阻種類繁多，型號齊全，型號命名一般都用封裝來表示。貼片壓敏電阻的封裝可以用兩種尺寸代碼來表示，一種英制代碼，另一種是米制代碼，都是由4位數(shù)字表示的。?

東沃電子自主研發(fā)、生產(chǎn)、銷售的貼片壓敏電阻，其封裝采用的就是英制代碼來表示的。目前市場上應用比較多的貼片壓敏電阻封裝有：0603、0805、1206、1210、1812、2220、3220等，具體型號有：
