The voltage rating is 250 VAC, which is typical for signal-level and low-power circuits in this pitch class.","metaTitle":"3-644457-6 TE Connectivity MTA-100 6-Pin Right-Angle Header","metaDescription":"Active 6-position unshrouded header, 0.100\" pitch, right-angle through-hole, tin-plated contacts.
