MAF1005PAD120CT000

Chip Ferrite Bead Overview

The MAF1005PAD120CT000 is a single-channel noise suppression filter manufactured by TDK Corporation, belonging to the MAF-P series. It utilizes ferrite bead technology housed in a compact 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component exhibits an impedance of 12 Ohms at a test frequency of 900 MHz and supports a maximum DC current of 6 A. Its maximum DC resistance is specified as 9 mOhms. The device operates within a temperature range of -55°C to +125°C.
