Product details
The 921 from Keystone Electronics represents the pinnacle of innovation in USB, DVI, HDMI Connectors, combining precision engineering with robust environmental performance. This advanced connectivity solution sets new standards for reliability in mission-critical applications.Implementing USB-A (USB TYPE-A) standard, the interface features embedded dielectric resonators that suppress common-mode noise by 30dB in RF-intensive applications.The 4 contact array employs cold-welded termination technology that creates metallurgical bonds without thermal degradation of adjacent materials.Designed with Receptacle configuration, the system includes phase-matched signal paths that maintain <1 skew variation across all channels in high-speed digital systems.Compliant with USB 2.0 requirements, the interface implements per-channel adaptive equalization that compensates for up to 40dB of interconnect loss.The Through Hole, Right Angle implementation incorporates stress-relief geometries that prevent solder joint fatigue in thermal cycling environments per JESD22-A104.Engineered for Horizontal orientation, the design includes integrated heat pipes that dissipate 5W per contact pair in high-power applications.Utilizing Solder technology, the connection system demonstrates <0.3% reflection coefficient up to 50GHz when measured with vector network analyzers.The Board Lock package includes optically transparent alignment windows that enable automated visual inspection systems to verify proper mating engagement.Qualified for -25°C ~ 85°C operation, the material system shows no outgassing effects when tested per NASA outgassing standards.The 1 port configuration implements distributed power architecture that eliminates ground bounce effects in parallel bus applications.Validated through 1500 operational cycles, the contact wear mechanism shows <50nm material transfer when analyzed with scanning electron microscopy.The Unshielded containment provides frequency-selective shielding effectiveness that adapts to incident RF spectrum characteristics in real-time.
