Rated at 600VAC and -55°C to 105°C, with a UL94 V-0 glass-filled thermoplastic housing, it suits general-purpose and industrial environments where flame rating and temperature range matter. ## Pitch, positions, and locking for harness fit The 0.156\" (3.96mm) pitch is the key dimension for PCB footprint layout and for selecting the mating MTA-156 receptacle housing and crimp terminals.","metaTitle":"1-640445-2 TE Connectivity MTA-156 Header 12 Pos 3.96mm","metaDescription":"1-640445-2 TE Connectivity AMP Connectors MTA-156 header, 12 positions, 0.156\" (3.96mm) pitch, shrouded-1 wall, friction lock, UL94 V-0.
