QTH-020-01-L-D-DP-A Description

Short technical summary and product information.

The Samtec QTH-020-01-L-D-DP-A is a differential pair array male connector from the QTH series. It features 40 positions arranged in 2 rows with a fine 0.50mm pitch, making it suitable for high-density board-to-board interconnections. The connector is surface mount and has a mated stacking height of 5mm, ideal for mezzanine applications.

 

The contacts are finished with 10.0µin (0.25µm) of gold, ensuring reliable signal integrity and corrosion resistance. The connector includes a board guide and a ground bus (plane) feature to aid in alignment and provide a low-impedance ground path. The height above the board is 4.06mm.

 

This connector is designed for differential pair signaling and is RoHS3 compliant, with an MSL rating of 1 (unlimited). It is commonly used in applications requiring high-speed data transmission in a compact form factor.
