For a given wire size, the MTA-156 contact's current capacity follows the standard derating curve in the TE application note. Mates with MTA-156 series receptacle housings and crimp terminals (e.g., 640550 series).","metaTitle":"1-640445-4 TE Connectivity MTA-156 Header, 14 Pos","metaDescription":"1-640445-4 TE Connectivity AMP Connectors MTA-156 header, 14 positions, 0.156\" (3.96mm) pitch, shrouded-1 wall, friction lock, UL94 V-0.
