Procurement Notes

Verify the specific center-tapped primary configuration and 1mH inductance requirements against circuit schematics. Confirm that the through-hole DIP package aligns with the target PCB footprint and manufacturing process. Ensure the operational temperature range of 0°C to 70°C meets the environmental conditions of the final assembly. Check for any recent product change notifications or end-of-life status updates from the manufacturer before placing orders.

Selection Notes

Select this component when a center-tapped primary is required for the specific application topology. Compare the 15Vµs ET rating against the voltage-time product requirements of the driving circuit to ensure adequate performance. Consider the through-hole installation method if surface-mount alternatives are not feasible for the mechanical constraints. Evaluate the physical size constraints against the available board space.
