Additional Details

The EHF-113-01-L-D-SM-LC connector features 26 total pins (13 per row, times 2 rows due to 'D' double row designation), and a surface mount termination style (SM). The 'L' designates the plating material, most likely gold. The connector body is typically made of high-temperature thermoplastic material, capable of withstanding reflow soldering processes. The connector is designed to mate with appropriate edge card connectors on printed circuit boards. The low lead coplanarity (LC) option helps ensure proper soldering and electrical connection across all pins. Samtec provides detailed datasheets with specifications on mating forces, durability, and environmental performance. These connectors are often used in demanding applications where high reliability and signal integrity are critical.

Electrical specifications generally include the current rating, voltage rating, and impedance. Mechanical specifications include the mating force, unmating force, and durability (number of mating cycles). Environmental specifications include the operating temperature range and humidity resistance. Careful consideration of these specifications is essential for selecting the appropriate connector for a given application.
