Specification
Conditions
Note 1: Includes temperature rise caused by current flow.
Note 2: The term "storage" refers to products stored for long period of time prior to mounting and use. Operating Temperature Range
and Humidity range covers non- conducting condition of installed connectors in storage, shipment or during transportation.
Note 3: This does not include the resistance of the conductor .
(
✽) Can accommodate type II cards only when standard mounting is
used and stand off is 0 mm.
