Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm packaging details and tolerance specifications. Ensure the procurement documentation explicitly references the SRF1260 series RoHS compliance status. Cross-reference the part number with official distributor catalogs to validate current availability and lead times before finalizing orders.

Selection Notes

Select this component when high current density and low profile are required in a dual-coil format. The 2.2 µH value and 10.9 A saturation rating make it suitable for high-frequency switching regulators. Consider the physical dimensions and thermal performance relative to the PCB layout constraints and ambient operating conditions.
