Electrical Characteristics,
Typical
AMP Z-PACK 2mm HM
Connector System offers
considerable benefits in
performance over other
2.00 [.079] systems. Tests
have shown values for
inductance, capacitive
loading and propagation
delay to be 18%, 13% and
18% lower respectively than
other 5 row systems.
Shield Types and Selection
Standard Version
5 row version gives 250 contacts/100
[3.937], suitable for rise times down to
100ps with cross talk <5% using a 4:1
signal/ground ratio (50 signal/100mm)
Reduced Cross Talk Version
Metal shield grounded to row c and to
the board (optional) reduces cross talk
in the d and e contacts by 25% to the
level of a and b. Allows increase in den-
sity to 100 signals/100 [3.937].
Ground Return Shields
Performance is enhanced suitable for
rise times down to 250ps by using extra
pin rows mating to shields on the recep-
tacle. Allows an increase in density to
75 signal/100 [3.937], reduces cross
talk by 30% and reduces single ended
impedance peaks in rows a and e.
Ground Return and Reduced
X-talk Shields
Increase performance to sub-nanosecond
rise times. When used with differential
pairs, improves cross talk by 30%,
lowers impedance peaks and reduces
propagation delay by 10%
EMI/RFI Shields
These shields, used with end caps,
totally enclose the connector and reduce
radiation by 20-30dB over the 100MHz-
1GHz range. These shields can be used
with reduced cross talk shields as
shown in the lower view.
