1.Michael Chen, Power Electronics Engineer, Industrial Drives
"Standardized on 3.96mm card edge connectors for our motor drive control cards. The 5A rating handles IGBT gate signals with margin, and the 1800V dielectric withstand provides critical safety margin for 480V AC drives."

2.Robert Zhang, Test Engineering Manager, Automotive Electronics
"Used in battery cycler test fixtures for EV modules. Gold-plated contacts maintain low resistance through 10,000+ cycles, ensuring accurate current measurements. Wire wrap option allows field modifications without soldering."

3.Lisa Park, Medical Equipment Designer, Diagnostic Imaging
"Essential for MRI power distribution cards. Pre-assembled card guides ensure proper alignment in shielded cabinets, and UL94V-0 housing provides flame resistance required for medical certification."

4.David Liu, Power Supply Designer, Industrial Automation
"Edge Mate wire-to-board version eliminated header costs while positive lock ensures connectors stay mated under vibration. Bifurcated terminals provide redundant contact paths for fail-safe operation in critical controls."
