The ACM series is a SMD filter from TDK, which is small in size and can be used for high-frequency signals.
The ACM series offers wire‑wound chip‑type common‑mode filters that are highly miniaturized yet maintain the required impedance characteristics. They provide a common‑mode impedance of 1000 Ω at 100 MHz while keeping differential‑mode impedance low, making them suitable for USB, IEEE1394, LVDS, and other high‑speed interfaces.
Technical data include detailed dimensions, impedance values for each part number, temperature range of –25 °C to +85 °C, and packaging options such as 180 mm reels with quantities up to 10 000 pieces. The filters comply with the RoHS Directive, ensuring they are free of restricted substances.

The filters have a common‑mode impedance of 1000 Ω at 100 MHz.
They operate from –25 °C up to +85 °C.
They are supplied on 180 mm reels, for example 2000 pieces per reel for the ACM2012 type.
