Product details

MTA-100 4-Position Header for Wire-to-Board

The 0.100" (2.54 mm) pitch matches standard MTA-100 receptacles, making it a direct mate for IDC or crimp housings in that family. All 4 positions are loaded, and the tin-plated contacts are rated for general-purpose use.

Through-Hole Mount and Solder Termination

The header mounts through-hole with solder termination. The contact length - post is 0.140" (3.56 mm), and the overall contact length is 0.535" (13.59 mm). The insulation height is 0.305" (7.75 mm), which affects clearance on the board. The housing is natural-colored thermoplastic rated UL94 V-0.

Frequently asked questions

Is 640454-4 shrouded?

Yes, it is shrouded on one wall. This provides partial pin protection during mating but leaves one side of the header exposed.
