Especificaciones
HIF3FC-40PA-2.54DSA(71) is a shrouded straight through-hole PCB header from Hirose Electric HIF3FC low-profile series, a standard 2.54mm pitch wire-to-board / board-to-board connector optimized for wave soldering mass production and compact stacked PCB interconnectionHIROSE Electric Group.
👉 It differs from half-pitch FX2 series connectors and right-angle HIF3FB variants. This straight through-hole header features dedicated anti-flux-wicking pin design, low-profile housing and full shroud anti-pin-bending protection, ideal for industrial control, test equipment and embedded mainboard internal multi-signal wiring.
Características principales
- Mechanical & Pin Structure Specs
- Contact count: 40 positions, 2-row layout, uniform 2.54mm (0.100″) mating & mounting pitch
- Mount type: Straight vertical through-hole THT soldering; DSA suffix means anti-flux-wicking pin construction to block solder flux climbing during wave soldering
- Low-profile housing: Header height 9.2mm, total stacked board mating height 12.2mm to save cabinet vertical space
- Full plastic shroud around pins, built-in polarizing key to prevent reverse insertion and pin damage
- Rated mating cycles: 500 plug/unplug operations for long-term equipment maintenance
- Matching counterpart: HIF3FC series shrouded receptacle for ribbon cable or daughter board connection
- Electrical Performance
- Rated current per contact: 1A
- Rated AC voltage: 200V; dielectric withstand voltage: 500V AC 1 minute
- Contact material: Copper alloy; contact plating: thin hard gold layer for anti-oxidation and stable contact resistance
