5-146278-2 Description

Short technical summary and product information.

The TE Connectivity 5-146278-2 is a vertical, unshrouded PCB mount header from the AMPMODU series. It has 2 positions in a single row with a 2.54mm (0.100 in) pitch, making it suitable for compact board-to-board or cable-to-board connections. The breakaway design allows the header to be snapped to the desired length for flexibility in prototyping or production.

 

This header uses through-hole solder termination and features square pins with a 0.64mm mating post dimension. The contacts are made of phosphor bronze with a tin plating thickness of 2.54 to 5.08 µm, and a nickel underplating. The housing is black LCP/LCP-GF rated UL 94V-0, with an operating temperature range of -65 to 105 °C. The product includes a board standoff for improved solder joint reliability.

 

Electrical ratings include a maximum current of 3A and an operating voltage of 30 VAC, suitable for signal-level applications. The connector is designed for parallel board-to-board configuration and is sealable with no mating alignment or PCB mount retention features. It is packaged in a carton of 500 pieces.
