5PCS ST1L05BPUR ST1L05BPU ST1L05B ST1L05 ST1L 05B 1L05B 1L05 DFN Product overview These five surface mount integrated circuits match the listed part numbers and come in DFN package. They are supplied as replacement components or for use in prototypes and small volume production where the DFN footprint and compact form factor are required. Key benefits Exact part number coverage: Includes multiple equivalent part number variants so you receive components that match the identifiers used in your design documentation and BOM. Space saving DFN package: Low profile, small footprint package that helps reduce board area and supports density PCB layouts. Ready for SMD assembly: Supplied in a DFN format suitable for reflow soldering and common surface mount handling processes. Convenient pack size: Five pieces provide spares for , evaluation, or low volume assembly without excess inventory. Why you need this product hard to source components on populated PCBs when the listed part numbers are specified. Keep consistent component versions across prototypes and production runs to avoid layout or footprint changes. Save board area and maintain a low profile in compact electronic designs where DFN packages are preferred. Compatibility and attributes Models included: ST1L05BPUR, ST1L05BPU, ST1L05B, ST1L05, ST1L 05B, 1L05B, 1L05. Package: DFN surface mount package for space constrained PCBs. Quantity: 5 pieces per . Mounting: Surface mount, compatible with reflow soldering processes and standard SMD assembly workflows. Footprint: Designed to match DFN pad patterns used for the listed part numbers; verify footprint dimensions against your board layout before assembly. Practical applications PCB and maintenance: failed or damaged parts on consumer electronics, communication modules, or industrial control boards that specify these part numbers. Prototyping and development: Test circuit revisions or evaluate component behavior without redesigning the PCB footprint. Small scale production: Populate low volume runs where the DFN package supports compact device layouts and professional assembly methods. What to check before ordering Confirm the exact part number and variant required for your circuit, as several closely related identifiers are covered. Verify that your PCB uses the DFN footprint corresponding to the part numbers listed. Ensure your assembly process supports DFN reflow and handling. This listing provides five DFN packaged integrated circuits matching the specified part numbers for , testing, or compact assembly needs.
