Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components Corp or their authorized distributors. Products acquired from unauthorized sources lack traceability and quality assurance guarantees. Confirm that the ordering suffix matches the required packaging format, such as Tape & Reel or Ammo Packing, prior to finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 10V reference with high power dissipation capabilities up to 5W. Ensure the design accounts for the specified thermal resistance limits and operating temperature ranges. Verify that the surge current requirements align with the device's non-recurrent square-wave pulse specifications for reliable circuit performance.
