Mill-Max has added a heavier gauge option to their line of SMT interconnect headers with the introduction of 349 and 449 series connectors. Their latest SMT male pin header strips feature sturdy .030 inch (0.76 mm) diameter pin tails, which plug easily into a variety of standard Mill-Max mating socket strips. The mating sockets are available in through-hole, right-angle, and SMT configurations. These header and socket combinations are rated at 4.5 A per pin for a 10°C temperature rise above ambient.
The headers feature a round, stub-tail termination providing the benefit of a reduced solder footprint inside the package outline. The .008 inch floating pin design compensates for the peaks and valleys found in uneven solder paste application on the board surface, promoting good solder joints. The .030 inch (0.76 mm) diameter pins provide extra strength for applications where there is the potential for rough handling, such as for field service repairs or blind mating situations.
With gold-plated pins assembled in high temperature thermoplastic, these headers are suitable for all SMT soldering operations and provide a highly reliable and durable connection.
