Procurement Notes

Verify the specific ordering suffix 'BK TIN/LEAD' to confirm the lead-tin plating finish required for your assembly process. Ensure compatibility with RoHS directives if lead-free components are mandated by your project specifications. Confirm availability status as high-voltage variants in this series may be subject to discontinuation notices or limited stock conditions.

Selection Notes

Select this component when a precise 68 V regulation point is necessary for through-hole designs. The DO-41 package offers robust mechanical stability for manual or standard automated insertion. Consider the 150 Ω dynamic impedance for noise-sensitive applications and verify that the 1.0 W power rating aligns with the expected thermal environment of the final enclosure.
