聲表面波濾波器 (TSF) 產品簡介
<
>
聲表濾波器是利用石英、鈮酸鋰、鈦酸鋇晶體，具有壓電效應的材料做成的。當晶體受到機械作用時，產生與壓力成正比的電場的現象。具有壓電效應的晶體，在受到電信號的作用時，也會產生彈性形變而發出機械波（聲波），即可把電信號轉為聲信號。由於這種聲波只在晶體表面傳播，故稱為聲表面波。
聲表面波濾波器的英文縮寫為 SAW Surface Acoustic Wave Filters，具有體積小，重量輕、性能可靠、不需要複雜調整的特點。
中國德鍵電子生產的聲表面波濾波器、聲表面波諧振器符合 RoHS 規範，Lead-Free 無鉛標準，使用 Lead-Free Logo 無鉛標誌。
提供完整貼片、插件聲表尺寸，頻率範圍齊全，提供聲表面波系列產品目錄下載。可依客戶的需求製造，若需特殊規格型式，請聯繫中國德鍵電子業務部。
