Notes:
1. Device mounted on ceramic PCB; 7.6mm x 9.4mm x 0.87mm with pad areas 25mm².
2. Short duration pulse test used to minimize self-heating effect.
3. When provided, otherwise, parts are provided with date code only, and type number identification appears on reel only.
4. f = 1kHz.
5. No purposefully added lead. Halogen and Antimony Free.
6. Product manufactured with Data Code V9 (week 33, 2008) and newer are built with Green Molding Compound. Product manufactured prior to Date
Code V9 are built with Non-Green Molding Compound and may contain Halogens or Sb₂O₃ Fire Retardants.
