Product details

12-Position, 2.50 mm Pitch, Tin-Plated Header

The 1-1744439-2 is a 12-position, single-row header from TE's Economy Power 2.5 series, designed for wire-to-board applications.

Glow Wire Compliance and Flame Rating

This header carries glow wire compliance per IEC 60335-1, a mandatory safety requirement for household appliances and lighting fixtures where the connector must withstand a glow-wire ignition test.

Termination is through-hole with a kinked pin, which provides retention during wave soldering before the solder joint solidifies.
