Tin is cost-effective for moderate mating-cycle applications — expect a few dozen cycles before wear becomes visible. The square male pins are copper alloy, rated at 250VAC. Current rating depends on the wire gauge used in the mating receptacle; the header itself is limited by the pin cross-section and the 105°C operating ceiling.","metaTitle":"2-644803-4 TE MTA-100 4-Pin Right-Angle Header","metaDescription":"2-644803-4 TE Connectivity MTA-100 shrouded header, 4 positions, 0.100\" pitch, right-angle solder tails, friction lock.
