- General-purpose signal and power routing
Procurement Notes
Verify the specific suffix 'L1R' against official Harwin documentation to confirm reel packaging and tape specifications. Ensure the selected variant matches the required 34-position count and vertical orientation. Cross-reference the datasheet for precise reflow soldering profiles compatible with the polyamide housing and gold-plated terminals to maintain connection integrity during assembly.
Selection Notes
Select this component when a high-density, vertical surface-mount solution is required for power or signal transmission. The 1.25 mm pitch allows for compact board layouts while maintaining robust electrical ratings. Consider the operating temperature range of -65°C to +150°C for applications subject to extreme thermal environments. Verify that the phosphor bronze contact material meets the mechanical retention requirements for the mating interface.
