QTH-090-04-L-D-A-TR Description

Short technical summary and product information.

The QTH-090-04-L-D-A-TR is a high-speed ground plane SMT header connector from Samtec's QTH series. It features 180 positions arranged in 2 rows at a 0.5mm pitch, making it suitable for dense board-to-board mezzanine applications. The connector uses outer shroud contacts with a gold finish (10µin) for reliable signal integrity.

 

The connector is designed for surface mount soldering and has a height above board of 15.24mm, with a mated stacking height of 16mm. It includes board guide and ground bus (plane) features to assist alignment and provide grounding. The contact finish thickness is 10µin (0.25µm) over the gold.

 

This connector is part of Samtec's Q Pairs® differential pair mezzanine connector family, supporting high-speed protocols up to 14 Gbps NRZ. It is supplied in tape and reel packaging with 100 parts per reel. The part is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited).

 

The QTH-090-04-L-D-A-TR is ideal for applications requiring high pin count and high-speed signal transmission in a compact footprint. Its robust design includes a ground plane for improved electrical performance.
