DF20F-20DP-1V(55)

The DF20F-20DP-1V(55) from Hirose Electric is a 20-position male pin header in a 2-row configuration with a 1mm pitch. This shrouded header (4-wall design) is intended for board-to-cable/wire applications, providing secure connections in compact electronic assemblies. It features phosphor bronze contacts with gold finish (0.203µm thickness), ensuring reliable signal integrity and corrosion resistance. The header is rated for 1A per contact and 100V, suitable for low-power signal and control circuits. Packaging is surface mount (SMD) with solder termination, and the part includes solder retention features for improved mechanical stability during reflow. The insulator is natural-colored polyamide (nylon) with a UL94 V-0 flammability rating, and the push-pull fastening type allows easy mating and unmating. Operating temperature spans -35°C to 85°C, accommodating a range of industrial and consumer environments. This header is RoHS3 compliant, meeting current environmental regulations for lead-free manufacturing. Its compact 1mm pitch design is ideal for space-constrained PCB layouts where high-density interconnections are required.

The board-to-cable/wire style enables use with discrete wire or ribbon cable connectors, making it versatile for internal wiring harnesses. Typical applications include office automation equipment, measuring instruments, and general electronic devices requiring reliable separable interfaces. Designers should note the surface mount footprint and 1.00mm row spacing when laying out PCBs.
