FEATURES
JC20 Series J type connectors are designed in accordance with
PCMCIA (Personal Computer Memory Card International
Association) and JEIDA (Japanese Electronic Industry Develop-
ment Association) standards. Designed for use with memory
cards, these high density, low profile connectors have 1.27mm
(.050") pitch and 68 contacts (2 rows). Socket connectors are
mounted on the card edge and pin connectors are on the PCB of
the mating system side. A push eject mechanism type is avail-
able for pin connectors.
• Conforms to PCMCIA/JEIDA (Ver. 4.1) Standard
Socket connectors for card side
• Low profile. Mating part is 3.3mm (.130") thick, and
card mounting part is 2.8mm (.110") thick. Minimum
applicable card thickness is 3.3mm (.130")
• Connecting area is protected from static electricity
• Connection with board circuits within cards is SMT
straddle type which is suitable for high density
mounting. Five terminal configurations are available
corresponding to PCB mounting positions and PCB
thickness
