Product details

0.100" pitch, 4-position shrouded header for MTA-100 wire-to-board

Through-hole solder termination with tin plating

The header terminates via through-hole solder posts, 0.140" (3.56mm) long, suited for standard PCB thicknesses. For higher cycle life or harsh environments, gold-plated variants in the MTA-100 series are available.

Active production with UL94 V-0 polyester housing

Current rating depends on the wire gauge of the mating terminal; the header itself is not the current-limiting element.
