QV1210H系列(lie)貼片壓敏電阻介紹(shao):
氧(yang)化(hua)(hua)鋅壓敏電阻是一種(zhong)以氧(yang)化(hua)(hua)鋅為主體、添(tian)加(jia)多(duo)種(zhong)金屬(shu)氧(yang)化(hua)(hua)物為添(tian)加(jia)劑、經(jing)過空(kong)氣中高溫燒結而制成的多(duo)晶半導體陶瓷元件。壓敏
電(dian)阻是(shi)一(yi)種(zhong)限壓(ya)型保護器件(jian)。壓(ya)敏電(dian)(dian)(dian)阻和(he)被保護電(dian)(dian)(dian)路(lu)(lu)(lu)元件(jian)并聯在電(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong),當電(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)出現雷電(dian)(dian)(dian)過(guo)電(dian)(dian)(dian)壓(ya)、靜(jing)電(dian)(dian)(dian)過(guo)電(dian)(dian)(dian)壓(ya)或瞬態操作過(guo)電(dian)(dian)(dian)壓(ya)
時,利用壓(ya)(ya)敏(min)電(dian)阻的(de)非線(xian)性(xing)(xing)特性(xing)(xing),壓(ya)(ya)敏(min)電(dian)阻會以納秒級(ji)時間的(de)響應速(su)(su)度將兩端電(dian)壓(ya)(ya)迅速(su)(su)下降鉗位到一個相對固定的(de)安全(quan)電(dian)壓(ya)(ya)值(zhi),從
而(er)避免被保護電路(lu)元件(jian)遭受過電壓的(de)沖擊(ji)而損壞。
當施加于(yu)壓(ya)(ya)(ya)敏(min)(min)(min)電(dian)阻器兩(liang)端電(dian)壓(ya)(ya)(ya)小于(yu)其壓(ya)(ya)(ya)敏(min)(min)(min)電(dian)壓(ya)(ya)(ya),壓(ya)(ya)(ya)敏(min)(min)(min)電(dian)阻器相當于(yu)10MΩ以上絕(jue)緣電(dian)阻;當在(zai)壓(ya)(ya)(ya)敏(min)(min)(min)電(dian)阻器兩(liang)端施加大于(yu)壓(ya)(ya)(ya)敏(min)(min)(min)電(dian)壓(ya)(ya)(ya)的過
電壓(ya)時,壓(ya)敏電(dian)阻器的電(dian)阻急劇(ju)下降呈現低阻態(tai),從而把電(dian)荷快速(su)導走,有效地保護(hu)了(le)電(dian)路中的其它元器件不(bu)致過壓(ya)而損壞。
多(duo)層片式壓敏電阻是貼(tie)片封裝的壓敏電阻器,采(cai)用多(duo)層獨石結構,具備寄生電感小、體積小、SMT效率(lv)高(gao)、響應(ying)時間短、工作溫度高(gao)、
保護(hu)能力(li)強的優勢。恭成(cheng)科(ke)技QV****H系列貼片壓敏(min)電(dian)(dian)阻(zu)應用(yong)于100V以內(nei)低(di)電(dian)(dian)壓電(dian)(dian)路,包括DC電(dian)(dian)源和低(di)頻信(xin)號(hao)線進行雷擊、浪(lang)涌(yong)防護(hu),
吸收并衰減(jian)脈沖能量,可以(yi)吸收線路內部產生的操作過(guo)電壓(ya)(整流、逆變換(huan)、變壓(ya)器產生的電磁脈沖和線路浪涌)及衰減(jian)后的雷電感(gan)
應過電壓,用(yong)作二級防護(hu)(可(ke)代替(ti)SMAJ/SMBJ的(de)TVS),同時部分應用(yong)于手(shou)機、LCD-TV/STB/電腦等的(de)通信接口進行ESD靜電防護(hu),替(ti)代
TVS使(shi)用。
