FBU321611T-520Y-S

Chip Ferrite Bead Overview

The FBU321611T-520Y-S is a multilayer ferrite chip bead manufactured by Cal-Chip Electronics, Inc. It operates as a single-function EMI suppressor in a 1206 (3216 Metric) surface mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 52 Ohms at 100 MHz and supports a current rating of 6A. Its maximum DC resistance is specified at 8 mOhm. Designed for power line applications, it utilizes multilayered ferrite technology to offer high impedance attenuation while maintaining excellent solderability and heat resistance for reflow and wave soldering processes.
