Product details

What the 3-Position Unshrouded Header Means for Your Board

In a low-vibration, benchtop or consumer-grade assembly this is fine, but for equipment subject to shock or cable tug, a shrouded header or a secondary locking mechanism on the receptacle side is worth considering.

For a BOM line that still calls out this exact order code, the only channel is independent distribution. No stock-holding claim — each lot is verified before commitment.
