CAN FD (CAN with Flexible Data-Rate)，是新一代車載網絡标準，比傳統的可以更高速（1Mbps以上）地收發(fā)更大容量數據（每幀最大64字節）的車載通信标準。DCMR (Differential to Common Mode Rejection）是指差模成(chéng)分變換爲共模成(chéng)分變換量，滿足CAN所使用的共模扼流線圈要求的DCMR特性被(bèi)分爲3個Class，DCMR Class3是指其中最嚴格的DCMR特性。
近年來，汽車行業追求更加安全舒适的駕駛體驗，通過(guò)引入ADAS（高級駕駛輔助系統）等，快速推進(jìn)汽車控制技術的高性能(néng)化發(fā)展。伴随著(zhe)當前的發(fā)展趨勢，要求實現車載通信的高速化，加速將(jiāng)數據傳輸速度從1Mbps（字節/秒）的Classical CAN 向(xiàng)更加高速的CAN FD轉換。
因此，在支持CAN FD的片式共模電感産品系列中，除了原有的100µH外，岑科還(hái)新增了51µH的ACML3225F-510-2P-T”。該産品可有效降低 CAN/CAN-FD等汽車内部網絡信号線的輻射噪聲。
CAN FD (CAN with Flexible Data-Rate) is a new generation automotive network standard that allows for higher-speed (above 1Mbps) transmission and reception of larger data payloads (up to 64 bytes per frame) in automotive communication. DCMR (Differential to Common Mode Rejection) refers to the transformation of differential mode components into common mode components, satisfying the DCMR requirements of the common mode chokes used in CAN. The DCMR characteristics are classified into three classes, with DCMR Class 3 being the most stringent.
In recent years, the automotive industry has been striving for a safer and more comfortable driving experience by introducing Advanced Driver Assistance Systems (ADAS) and rapidly advancing the performance of automotive control technologies. With the current trend, there is a demand for higher-speed communication in automotive systems, driving the transition from the Classical CAN's 1Mbps data transfer rate to the faster CAN FD.
Therefore, in the series of chip-type common mode inductors that support CAN FD, in addition to the existing 100µH variant, we have also introduced a new variant, the "ACML3225F-510-2P-T" with a value of 51µH. This product effectively reduces the radiated noise of internal automotive network signal lines such as CAN/CAN-FD.

注：IEC62228-3實現了CAN-FD針對(duì)專用共模電感所要求的DCMR Class3。IEC62228-3是IEC（International Electrotechnical Commission即國(guó)際電工委員會(huì)）制定的有關電氣和電子技術的标準之一。
