Currently, I'm using standard headers with a pitch of 2.54mm (0.1"). These are quite big on my boards. Are there any surface mount standard headers, say in 0.05"?
They should be stocked by Newark (and Farnell/Element 14) in 2-10 positions, click the distribution links from the GCT pages (look for the green tick) to navigate to the exact range. If you can't find what you seek MOQ's are circa 1,000+ to deal direct/vis distribution.
Actually 1.27mm (.050") connectors are superseding 2.00mm (.079") in volume sales, not by much, but they shade it. Anyway, it's horses for courses so pick whichever ones you like.
GCT also product economical 1.00mm (.039") straight SMT headers which are freely available from Newark/Farnell in 2-10 positions.
