USLS21 Series
Low Profile Stack Mating Type
0.4 mm pitch connector for micro coaxial cables (connection by soldering)/Stacked mating type.
Key Features
Compact Connector with 1.65 mm Stack Height
- It has an effective mating length of 0.35 mm, a low profile of 1.65 mm stack height, and a 3.05 mm mating width. Applicable for high-density printed circuit boards.
- The cable harness can be passed through thin tube of 4mm diameter.
- Lead-free product
Improved Product Strength, Transmission Characteristics, Noise Reduction
- The board-side connector is surrounded by a metal shell to improve noise reduction, product strength, and to strengthen grounding.
- Ground terminals are provided at multiple points to improve transmission and EMS characteristics.
- A nickel barrier is placed on the board-side contact to prevent the solder from lifting.
