280521-1 Description

Short technical summary and product information.

The TE Connectivity 280521-1 is an AMPMODU II series shrouded header designed for board-to-board or cable interconnect applications. It provides 24 positions arranged in 2 rows with a standard 2.54mm (0.100") pitch, making it suitable for dense PCB layouts.

 

Key specifications include a current rating of 3A and voltage rating of 40V. Contacts are made of brass with a tin finish (3.00µm thickness) for reliable conductivity. The header features a 3-wall shrouded housing with a detent lock fastening type for secure mating.

 

The through hole termination style allows for wave soldering up to 265°C. The black thermoplastic insulator meets UL94 V-0 flammability rating and supports an operating temperature range of -40°C to +80°C.
