QSH-090-01-L-D-A-K-TR Description

Short technical summary and product information.

The Samtec QSH-090-01-L-D-A-K-TR is a 180-position, 2-row receptacle connector with center strip contacts, featuring a 0.50mm pitch. It is designed for mezzanine board-to-board applications and supports multiple stacking heights: 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm. The connector is surface mount with a lead style of 01 and includes a polyimide pick-and-place pad, board guide, and ground bus plane.

 

Electrical specifications include a current rating of 2A per pin (2 pins powered) and 25A per ground plane (1 ground plane powered). The voltage rating is 175VAC at 5mm stack height. Operating temperature range is -55°C to +125°C. The contact material is phosphor bronze with a gold finish of 10µin (0.25µm) on the contact area and matte tin on the termination tails. The insulator is liquid crystal polymer.

 

The connector is lead-free solderable and rated for 100 mating cycles. SMT lead coplanarity is maximum 0.15mm for the 090 lead style. Packaging is tape and reel (TR suffix). This connector is suitable for high-density board stacking in applications requiring reliable signal integrity and power distribution.
