Part Numbering System
Q-Tech Corporation assigns a custom MCM part number for each of the customer’s specification or application. The unique part
numbering system allows Q-Tech to design, select appropriate technology (packaging, supply current, operating temperature, vibration
and shock requirement, etc.) to tailor customer’s specific needs. The part is available in standard Full Military screening (-M) per
MIL-PRF-55310, product level B. Sample part number MCM7933-3M
