Product details

Picoflex PF-50 18-Position Header — Board-to-Wire Signal Interconnect

The 0903259018: The shrouded 2-wall housing protects the male blade contacts during mating and prevents misalignment.

Pitch and Footprint — What the 1.27 mm Spacing Means for the Board

At 1.27 mm pitch, this header saves board real estate compared to 2.54 mm pitch headers — roughly half the linear width per circuit. The 18 positions fit in a footprint about 22.9 mm wide, which suits dense PCB layouts where routing channels are tight. Post-plating is tin, compatible with lead-free wave solder profiles.

This header mates with Picoflex PF-50 receptacle housings and crimp terminals (same 1.27 mm pitch series).

Frequently asked questions

What is the mating connector for 0903259018?

The mating half is a Picoflex PF-50 receptacle housing (1-row, 18-position, 1.27 mm pitch) with the corresponding crimp terminals. The push-pull latch engages without tools.

What is the pitch and current rating of 0903259018?

The tin-plated contacts suit signal-level current, not power distribution.
