It is supplied in a 10-WFQFN package with a 10-QFN (2x3) supplier device package, surface-mount mounting. ## Package and board-fit considerations The 10-WFQFN package (2x3 mm body) is a fine-pitch, thermally enhanced QFN. The exposed pad on the underside must be soldered to a thermal land on the PCB to achieve the rated thermal performance. The 0.50 mm pitch requires careful solder-paste stencil design to avoid bridging between adjacent pads.","metaTitle":"STMicroelectronics STEF512PUR Power Management, 10-QFN","metaDescription":"STMicroelectronics STEF512PUR power management IC, 10-WFQFN package, ROHS3 compliant.
