晶體諧振(zhen)器的(de)應用產品(pin)

石英晶體諧振(zhen)器根據其外型結構不同可(ke)分為HC-49U、HC-49U/S、HC-49U/S·SMD、UM-1、UM-5及柱狀晶體等。

HC-49U適用于具有寬闊(kuo)空間的電(dian)(dian)子(zi)產(chan)品如(ru)通信設備、電(dian)(dian)視機、電(dian)(dian)話機、電(dian)(dian)子(zi)玩(wan)具中(zhong)。

HC-49U/S適用于空(kong)間(jian)高(gao)度受到限制的各(ge)類薄型、小型電(dian)子(zi)設備(bei)及產品中。

HC-49U/S·SMD為(wei)準表(biao)面貼裝(zhuang)型產品(pin)，貼片晶(jing)體諧(xie)振器(qi)加工，適用(yong)于各類超薄(bo)型、小型電腦及(ji)電子設備中(zhong)。

柱狀石英(ying)晶體諧振器適用(yong)于(yu)空間狹小的穩頻計(ji)時電子產品如計(ji)時器、電子鐘、計(ji)算器等。

UM系列產(chan)品主要應用于移動(dong)通訊產(chan)品中，如(ru)BP機、移動(dong)手(shou)機等。

石英晶體諧振器電容

晶(jing)振(zhen)(zhen)的(de)(de)負(fu)載(zai)電(dian)(dian)容(rong)(rong)(rong)(rong)有(you)高、低兩類之別。低者一般(ban)僅為十幾至幾百PF，貼片(pian)晶(jing)體諧(xie)振(zhen)(zhen)器(qi)(qi)原(yuan)廠，而高者則(ze)為無窮大，兩者相差懸殊，決(jue)不(bu)能(neng)混用，貼片(pian)晶(jing)體諧(xie)振(zhen)(zhen)器(qi)(qi)，否則(ze)會使(shi)振(zhen)(zhen)蕩(dang)頻率偏(pian)離。兩類不(bu)同負(fu)載(zai)電(dian)(dian)容(rong)(rong)(rong)(rong)的(de)(de)晶(jing)振(zhen)(zhen)使(shi)用方式(shi)絕然不(bu)同。低負(fu)載(zai)電(dian)(dian)容(rong)(rong)(rong)(rong)晶(jing)振(zhen)(zhen)都串(chuan)聯(lian)(lian)幾十pF容(rong)(rong)(rong)(rong)量(liang)的(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)；而高負(fu)載(zai)電(dian)(dian)容(rong)(rong)(rong)(rong)晶(jing)振(zhen)(zhen)不(bu)但不(bu)能(neng)串(chuan)聯(lian)(lian)電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)，還須并(bing)聯(lian)(lian)數pF小容(rong)(rong)(rong)(rong)量(liang)電(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(外(wai)電(dian)(dian)路的(de)(de)分布晶(jing)振(zhen)(zhen)電(dian)(dian)容(rong)(rong)(rong)(rong)有(you)時也(ye)能(neng)取代(dai)這個(ge)并(bing)聯(lian)(lian)小電(dian)(dian)容(rong)(rong)(rong)(rong))
