EMI filters save space in power designs
Surface-mount common-mode filters offer maximum radiation noise suppression for power lines, audio/video applications and car multimedia.
New from TDK Corp, the ACM4520-901 and ACM4520-142 surface-mount common-mode filters are designed to offer maximum radiation noise suppression for power lines, audio/video applications and car multimedia The ACM4520-901 offers 900ohm common-mode impedance at 100MHz and the ACM4520-142 offers 1400ohm common-mode impedance at 100MHz, with each component measuring just 4.7 x 4.5 x 2.0mm

Component library is free to design customers
TDK and Ansoft Corporation have announced the release of a new library for TDK's capacitor, inductor, common mode filter, and ferrite bead components for use in Ansoft Designer.
The low profile and the reduced footprint are critical features for space constrained power supplies and power lines.
The ACM4520-901 has a typical DC resistance of 35mohm with a rated current of 2.0A, whereas the ACM4520-142 has a typical DC resistance of 45mohm with a rated current of 1.5A.
Both parts in the series have a rated maximum voltage of 50V.
Several other variants of the ACM4520 series are planned to extend the selection of maximum currents available, and to fulfil the requirements of a broad range of applications.
The ACM4520 series is RoHS compliant, completely lead-free and has a specified operating temperature from -40 to +85C.
The series is available now, supplied either in volume tape-and-reel packaging or in sample books.
