低通濾波器是種數(shù)字信號處理濾波器，將控制信號通過一些濾波器，只接受某些諧振頻率之下的信號通過，通過清除高頻信號，過濾控制信號中的高頻噪音或干擾信號，從而使得輸出信號更加平整、更加穩(wěn)定。這種諧振頻率一般稱為濾波器的諧振頻率或截止角頻率，一般以赫茲或弧度為單位/秒來表示。

KR Electronics低通濾波器SMD能夠利用各種電源電路去實現(xiàn)，包含差分放大器、運算放大器、濾波電容、功率電感等。

KR Electronics低通濾波器SMD根據(jù)客戶需求個性定制低通濾波器貼片的參數(shù)。還能通過封裝進(jìn)行調(diào)整。表面貼裝型一般用于封裝形式，連接器也同樣如此。
