3-644456-9 Description

Short technical summary and product information.

The TE Connectivity 3-644456-9 is a 9-position single-row unshrouded header designed for board-to-cable/wire connections. It features male pins with a square contact shape and tin-plated copper alloy contacts, with a contact finish thickness of 150µin (3.81µm). The pitch is 2.54mm (0.100"), providing compatibility with standard spacing requirements.

 

The header is through-hole mounted with solder termination, making it suitable for permanent PCB connections. The insulation is made of natural thermoplastic with a UL94 V-0 flammability rating, ensuring safety in various applications. The insulation height is 2.54mm (0.100").

 

Electrically, the header is rated for 250VAC operation and an operating temperature range of -55°C to 105°C. The current rating varies by wire gauge, so designers should refer to manufacturer guidelines for specific current capacities. The overall contact length is 0.505" (12.83mm), providing adequate insertion depth.
