Product details
Amphenol RF's 903-373J-51A redefines reliability standards in Coaxial Connectors (RF) connectivity solutions. Developed for aerospace-grade signal integrity, this connector maintains phase coherence across extended temperature cycles while minimizing skin effect losses.The SMB interface configuration delivers consistent 50 characteristic impedance, critical for high-speed digital RF systems. Its elliptical contact design reduces surface wave propagation.Utilizing Jack, Male Pin architecture, the connector achieves >65dB isolation between adjacent ports. The tri-material contact system prevents fretting corrosion.Solder methodology ensures gas-tight connections with <0.1pF parasitic capacitance. The crimp profile is optimized for {Cable Group} dielectric compression.With Solder technology, the connector exhibits <2nH grounding inductance. The quad-segment shielding provides omni-directional EMI suppression.The 50Ohm matched design features tapered dielectric transitions to minimize return loss. Time-domain reflectometry shows <3% impedance deviation across {Frequency - Max} bandwidth.The Through Hole, Right Angle configuration integrates strain relief that exceeds ICE 60332-1-2 flame ratings. The captive hardware prevents loose parts in vibration environments.Snap-On engagement system provides audible mating confirmation with <1.5N engagement force. The anti-decoupling mechanism prevents spontaneous disconnection.Characterized up to 4 GHz, the connector demonstrates group delay variation <5ps across the band. The low-dispersion design is ideal for wideband radar applications.The 1 configuration features individual port identification for automated testing systems. Each channel maintains <-60dB cross-port isolation.Silver coding follows NATO STANAG 3910 specifications for rapid visual identification. The ceramic-loaded composite resists UV degradation.The Brass formulation provides <0.5 in surface roughness for consistent RF performance. Material properties are verified per ASTM B36 standards.
