關於 被動元件
被動元件在不提供主動增益的情況下,用於儲存、調整、濾波、調諧或傳遞電能與訊號。Antrex 的 Passive Components 類別包含電容器、電感/扼流圈/線圈、晶體/振盪器/諧振器、濾波器、電位器與可變電阻,以及音訊/訊號變壓器。這些元件廣泛用於電源轉換、去耦、定時、EMI 抑制、阻抗匹配、訊號調理與類比調整,常見於工業電子、通訊設備、汽車系統、消費產品、電源與嵌入式硬體。
選型時應先依電路功能進入正確子類。電容器需比較電容量、額定電壓、介質技術、公差、ESR、紋波電流、溫度與壽命;電感、扼流圈與線圈則需確認電感值、直流電阻、飽和或額定電流、磁芯材料、自諧振頻率與屏蔽。定時元件要核對頻率、頻率容差/穩定度、負載電容、驅動電平、供電與封裝。濾波器應依類型、截止或中心頻率、阻抗、插入損耗、衰減、頻寬與電流/功率能力選擇。電位器與可變電阻需確認阻值、曲線、功率、調整方式、機械壽命與安裝尺寸;音訊與訊號變壓器則需比較匝數比、阻抗、頻率響應、隔離、功率與繞組配置。所有被動元件還應確認封裝、端接、溫度係數、環境等級、認證與生命週期,名義數值相近的器件在高頻、高紋波、高溫或瞬態條件下可能有很大差異。
