Product details

Board Fit and Footprint – 1.25mm Pitch, 4 Positions

Pick-and-place features and solder retention aids mean this header is designed for automated SMT assembly: the part stays seated during reflow, and the solder retention features reduce tombstoning risk.

For a 1.25mm pitch system, expect a few amps per circuit with 28-30 AWG; the voltage ceiling is 50VAC/DC, which covers low-voltage signal and power distribution in consumer, industrial, and automotive auxiliary circuits.

Temperature and Flammability – Where It Can Live

The UL94 V-0 glass-filled nylon housing means the connector itself won't sustain a flame — a requirement for equipment that must pass a flammability test.

Sourcing and Lifecycle – Active, Sourced per RFQ

No end-of-life notice or successor has been published.
