1. DF81D-50P-0.4SD Characteristics and Advantages

DF81D-50P-0.4SD features a 50-pin, 0.4mm pitch design, with a length of approximately 24.8mm and a thickness of about 0.82mm, greatly saving space within the system. Its standard transmission speed reaches up to 5.4 Gbps, compatible with high-speed interfaces such as eDP and MIPI, and recommended for use with miniature coaxial cables with 34-46 AWG. Through a lock structure, gold-plated contacts, and enhanced shielding design, it achieves high reliability, vibration resistance, and stable signal transmission, widely used in intelligent terminals, vehicle-mounted electronics, and industrial automation applications.

Section 2: Attenuation Characteristics of Miniature Coaxial Lines

The center conductor of a miniature coaxial cable is typically AWG 30-46, with an outer diameter of only 0.22-1.16 mm, offering excellent electromagnetic shielding and flexibility. In high-frequency signal transmission, although increased frequency leads to increased attenuation, good signal integrity can still be maintained over short distances. For example, within the DC-6 GHz frequency range, the typical insertion loss of a miniature coaxial cable is usually less than 3 dB. A few centimeters of cable can meet the needs of high-frequency short-distance high-speed transmission, ensuring stable and reliable data.
