Compatible with 2 mm
equipment practices per
IEC 61076-4-101
One-piece molded
housing — fewer parts to
assemble to PCB
Very high current density —
18 Amps per contact on each
contact in an 8-position
(2 x 4) connector
4 PCB tails distributes the
current with just 4.5 amps
per plated through hole
Hot-pluggable contact
design reduces contact
degradation associated with
live PCB insertions /
extractions
Two-levels of contact
sequencing for mate-first-
break-last operation
Dimensions are in inches and
millimeters unless otherwise
specified. Values in brackets

Power Connectors & Interconnection Systems
MINIPAK HDE Connectors
The new MINIPAK HDE
connector is the latest high
current power module
designed to serve in both
backplane power distribu-
tion and general PCB-to-
PCB applications. It was
designed to complement the
most popular high-speed
backplane connectors
offered by Tyco Electronics,
including HM-Zd, Z-PACK
TinMan and MULTIGIG RT
connectors.
The two-row configuration
offers a benefit to the PCB
designer. The power can
be fed from either the top or
bottom row, with the return
path routed through the
other remaining row.
Alternatively, the same volt-
age rail can be routed to

both the top and bottom
rows and the return path
can be routed to both the
top and bottom rows of
adjacent contacts.
The two row configuration
offers the additional benefit
of occupying just half the
linear PCB edge space of
other types of board-to-
board power modules.
The low mating force con-
tact reduces the moment /
stresses on the connector
during mating and reduces
the plating wear for long-
term reliability.
The MINIPAK HDE connec-
tor has two-levels of blade
lengths to provide mate-
first-break-last operation
for hot swap operation.

In addition, in the event the
connector is used to mate
or un-mate to a live load,
the sacrificial contact tip
absorbs the arc to keep the
remaining contact mating
surfaces free of damage.
This “hot-plug” contact
design has been approved
by UL for current interrupt
applications.
All MINIPAK HDE connec-
tors are easily applied to
the PCB with common
“flat-rock” seating tools.
The connector mates with
