HAR3927DJ-4301R-8-00-HATF-0403 – TDK MICRON

The HAR3927DJ-4301R-8-00-HATF-0403, manufactured by TDK, is a monolithic 3D Hall-effect sensor designed for contactless position detection. This device integrates three orthogonal Hall elements, signal conditioning circuitry, and digital logic to provide simultaneous measurement of magnetic field components along the X, Y, and Z axes. The sensor incorporates advanced offset cancellation techniques to minimize errors due to temperature drift and process variations. The 4301R variant indicates a specific sensitivity range and output characteristic, while the -8 denotes an SOIC-8 package. The HATF suffix specifies a particular factory trimming configuration for optimized performance within a defined magnetic field range. The 0403 portion of the part number likely represents a date code or internal tracking identifier. It requires a regulated supply voltage, typically 3.3V or 5V, and provides a digital output representing the measured magnetic field vector.
