Standard SMC connectors Technical characteristics
Current carrying capacity
The current carrying capacity is limited by maximum temperature
of materials for inserts and contacts including terminals.
The current capacity-curve is valid for continuous, not interrupted
current-loaded contacts of connectors when simultaneous power
on all contacts is given, without exceeding the maximum tempera-
ture.
Control and test procedures according to DIN IEC 60 512.
Contact arrangement View from termination side

Working current
see current carrying capacity chart
Stamped contacts 6.5 A max.
Test voltage U
r.m.s. 1 kV
Clearance and creepage ≥ 1.0 mm
Contact resistance ≤ 10 mΩ
Insulation resistance ≥ 10 10 Ω
Temperature range -55 O C … +125 O C
during reflow soldering max. + 240 O C for 15 s
The higher temperature limit includes the local ambient and
heating effect of the contacts under load. All connectors are
suitable for standard reflow processes.
