Overview

Macro X is a 4 lead component package the is used for RF transistors1. As of 2022, the package seems obsolete.

Synonyms:

  • Micro-X Ceramic2
  • Package Style M2381

Similar To:

  • Macom CASE 305A-013
  • Macro T1

Microsemi’s BJT pinout for this package connected the longest lead to the collector, the lead opposite this to the base, and the other two leads to the emitter1.
