Current rating depends on wire gauge in the mating receptacle — the header itself is not the limiting factor. Voltage rating is 250 VAC, consistent with the MTA-100 family's signal-level duty. ## Active production — no cross-reference hunt needed RoHS3 compliant and UL94 V-0 rated. The natural thermoplastic housing is unpigmented — no colourant to affect dimensional stability.","metaTitle":"3-644456-9 TE Connectivity MTA-100 Header, 9 Pos","metaDescription":"3-644456-9 TE Connectivity AMP Connectors MTA-100 unshrouded header, 9 circuits, 0.100\" (2.54 mm) pitch, through-hole, tin plating.
