PICMG 3.8 POWER CONNECTOR

December 15, 2011

Positronic’s Scorpion Series chosen for PICMG 3.8
AdvancedTCA was developed to define next generation carrier-grade telecommunications
equipment. ATCA architecture enables increased mobility and improves reliability, availability,and serviceability. The ATCA specification allows the standard to keep up with an evolving andcompetitive industry.
One of the latest ATCA evolutions is the PICMG 3.8 standard. PICMG 3.8 specifies Zone 3
requirements for rear transition modules in ATCA systems. The standard also addresses power,cooling, and keying issues. This addition to the family of PICMG standards supports the use of
ATCA in a variety of applications outside of telecommunications.
One of the key features of PICMG 3.8 is the definition of a power and system management
connector. This allows a consistent means of supporting generic system requirements, whileallowing the flexibility to utilize application specific connectors as needed.
Positronic’s Scorpion connector series was chosen as the power and system management
connector for the 3.8 standard. The Scorpion’s high-density packaging of miniature power
contacts made it the preferred choice for this application.
The PICMG 3.8 power connector has 16 contacts rated at 3 amperes each at a maximum
temperature rise of 30 degrees C; all contacts energized. Contact resistance is 6 milliohms
maximum. The connector package offers blind mating capability and is only19.8 mm wide.
Contact termination types include right angle solder and straight press-fit.
