低通濾波器是種數(shù)字信號(hào)處理濾波器，將控制信號(hào)通過一些濾波器，只接受某些諧振頻率之下的信號(hào)通過，通過清除高頻信號(hào)，過濾控制信號(hào)中的高頻噪音或干擾信號(hào)，從而使得輸出信號(hào)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(shí)現(xiàn)，包含差分放大器、運(yùn)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(gè)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。
