Procurement Notes

Verify the specific suffix designation to confirm the surface-mount variant against through-hole alternatives within the same series. Ensure that the center-tapped primary specification aligns with the target circuit topology requirements. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential product change notifications affecting physical dimensions or electrical characteristics prior to final procurement.

Selection Notes

Select this component when a surface-mount solution is required for pulse isolation with a center-tapped primary. Compare the 20 V/µs volt-second rating against the maximum expected voltage-time product in the application to prevent core saturation. Evaluate the physical footprint constraints against the 9.52 x 9.00 mm dimensions to ensure compatibility with the printed circuit board layout and available mounting space.
