Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and insulation color specifications. Confirm that the target application environment remains within the operational temperature range of -40°C to 105°C. Ensure the PCB thickness falls within the specified tolerance of 1.37mm to 1.78mm for proper mechanical engagement. Check RoHS compliance status against current regulatory requirements for the destination market.

Edgeboard Connectors Selection Notes

Select this component when a 70-position dual-edge interface is required with a 3.96 mm pitch. Consider the 5 A current rating and 1800 VACrms voltage capability for power and signal integrity needs. Evaluate the panel mount style and vertical orientation against available board space constraints. Compare against other 305 series variants if different position counts or termination styles are necessary.
