我們收到一位客戶對 B72214P 系列壓敏電阻的直徑差異懷疑，例如零件編號：B72214P2271K101。我們與製造商 EPCOS - TDK Electronics 進行了核實，以澄清這個憂慮。
據 EPCOS - TDK 稱，規格書中使用的術語「標稱/公稱 (Nominal)」是指近似尺寸，而不是精確尺寸。標稱/公稱直徑14毫米表示直徑約14毫米，允許略有變化。
此外，您也可以在圖紙中檢查壓敏電阻的最大直徑是否顯示為 Wmax：
除此之外，這些壓敏電阻還有精簡(Compact)尺寸，例如：
-
MP Compact 系列 (B72314P2)：B72314P2271K101
該零件尺寸較小（Wmax = 13.5mm） -
MP 標準系列 (B722)：B72214P2271K101
該零件 Wmax = 16.0mm
