This document describes the features and characteristics of the A297 0.5mm Pitch SMT Board to Board Connector DF12 Series, including various stacking height options, compatibility with automatic mounting, and provision of metal fittings to prevent solder peeling.
The DF12 series from HRS offers ultra‑miniature 0.5 mm pitch SMT board‑to‑board connectors with selectable stacking heights of 3.0 mm, 3.5 mm, 4.0 mm and 5.0 mm. The connectors are suited for mobile phones, LCDs, optical disks and notebook PCs and feature a vacuum pick‑up area for automatic mounting.
The handbook details electrical specifications (rated current 0.3 A, rated voltage 50 V AC, operating temperature –45 °C to +125 °C), material construction (polyamide insulator, phosphor‑copper contacts with gold plating), packaging (embossed tape, 1000 pcs/reel) and recommended soldering profiles (290 °C ± 10 °C, ≤2 s). It also includes ordering information, PCB footprint recommendations, and safety precautions for handling the contacts.
