Discuss This Tray for Your Application

Mention MC-77221 when you contact us.

A starting point for your device

The MC-77221 uses pockets that are closer to square than some of the longer rectangular designs in this family. Ten positions fit within the 8.500″ × 6.000″ tray, with a 0.200″ reference cavity depth.

A nearly square component may still need a defined orientation because of leads, terminals or a keyed corner. Send those details so we can review the complete outline and seating position.

If your device differs from the reference application, contact us anyway. We can discuss whether this tray, another existing design or a custom packaging solution is worth exploring.

Use these reference dimensions for an initial size comparison. Actual fit depends on the device profile, pin clearances and selected material. If your device is close to these dimensions, contact us to review the fit.

Look beyond the overall size

The line view shows the compact pocket shape and end recesses. We can assess how local features interact with a keyed or asymmetric component.

Tell us how the tray will be used, whether for work-in-process handling, storage or a shipping application. We can then review the tray as part of the complete packaging requirement.

Choose a material for your application

MC-77221 is available in both black conductive and clear antistatic material. Tell us about your ESD requirements, handling environment and any need to see the device through the tray so we can discuss the appropriate option.

Black conductive

An option for applications requiring conductive tray material. Share your material or ESD specifications so we can review the requirements with you.

Clear antistatic

An option when clear material is useful for viewing the device. We can discuss the antistatic material requirements alongside fit and handling.

Could MC-77221 work for your device?

You do not need a complete specification to begin. Send what you have, and we can help identify the details needed to assess the tray and prepare a quotation.

  • A device drawing, photograph, package outline or description
  • Any known dimensions, pin clearances or handling concerns
  • Your material preference or ESD requirements, if known
  • Estimated quantities and timing

Please include MC-77221 in your inquiry so we can refer to this tray design.
