A newly-optimized footprint simplifies signal path routing and enables a migration path to 112G. STRADA Whisper R connectors utilize the same mating interface and are backwards compatible with our existing STRADA Whisper connectors. The STRADA Whisper product family operates with extremely low noise, low insertion loss and little to no skew—all of which provide system architects with design flexibility and high design margin. With 92 Ohm impedance, STRADA Whisper R connectors support both 85 Ohm and 100 Ohm impedance system requirements. STRADA Whisper R connectors are a more cost effective solution thanks to a new design and a fully automated assembly process. **te.com/products/stradawhisper** DATA AND DEVICES /// STRADA WHISPER R BACKPLANE CONNECTORS ## **STRADA Whisper R Backplane Connectors** ## SIGNAL INTEGRITY _Electrical models are available upon request_ ## **Technical Detail** - Data Rate: 56G PAM4 - Impedance: 92 Ohm - PCB Termination: Press-fit - Electrical: - Signal LLCR Max Initial: 200 mOhm - Insulation Resistance: 1000 M-ohm min - Voltage Rating: 80 Vac - Current Rating: 0.5A per contact - Mechanical: - Wipe Length: 2.50 mm - Mating Force: 2.50 N max per differential pair including ground - Unmating Force: 0.31 N min per differential pair including ground - Press-fit insertion force: 17.8 N max per contact - Product Specification: 108-140186 - Application Specification: 114-32029 - PCB routing guide available upon request ## AVAILABLE PART NUMBERS |**TE Part Number**|**Connector Type**|**Configuration**| |---|---|---| |2356426-1|Receptacle|4x4| |2356429-1|Receptacle|4x6| |2329739-1|Receptacle|4x8| |2187724-1|Header|4x4| |2187726-1|Header|4x6| |2187799-1|Header|4x8| ## **TE Technical Support Center** |**TE Technical Support Center**|**TE Technical Support Center**| |---|---| |USA:|1.800.522.6752| |Canada:|1 .905.475.6222| |Mexico:|52.0.55.1106.0800| |Latin/S.
