42840-3

TE Connectivity AMP Connectors's 42840-3 redefines Card Edge Connectors - Contacts technology for high-speed computing applications. This PCIe 5.0 compliant connector supports 32GT/s data rates with exceptional signal integrity. Its innovative shielding design reduces crosstalk by 40% compared to previous generation solutions.Featuring Non-Gendered architecture with differential pair alignment, the connector maintains <3% intra-pair skew. The precision-machined contacts provide consistent impedance (85 5%) across all channels.Designed for 18-22 AWG high-speed cables, the contact geometry minimizes insertion loss to <0.3dB/inch at 16GHz. The optimized via transition reduces stub effects in multilayer PCB designs.The Crimp process utilizes selective gold plating that reduces skin effect losses. This technique achieves 25% better high-frequency performance than conventional full-plating methods.The Phosphor Bronze alloy combines high conductivity with minimal dielectric absorption. Material characterization shows <0.1% signal attenuation at millimeter-wave frequencies.With Gold surface treatment, the contacts exhibit ultra-low passive intermodulation (PIM <-160dBc). The proprietary plating sequence prevents intermetallic diffusion at elevated temperatures.The 3.00µin (0.076µm) is optimized for high-frequency current distribution. Time-domain reflectometry confirms impedance uniformity within 2% across the entire connector length.
