1.27mm Pin Headers Preci-Dip 1.27mm Pin Headers are single-, double-, and triple-row straight solder tail vertical headers with high-temp thermoplastic insulators, making them suitable for conventional wave and reflow soldering. These ultraminiature through-hole connectors accept 0.41mm mating pin diameters and provide high-density interconnects for tightly packaged PCBs. Preci-Dip 1.27mm Pin Headers feature a -55°C to +125°C operating temperature range, 1000VRMS minimum dielectric strength, and 1A rated current. These connectors meet UL 94V-0 standards and are RoHS compliant.
