0.087'' Non-Magnetic Semi-Rigid Coax Cable 50 Ohm SR-086C-SP Silver Plated RF Cable

The SR-086C-SP is a precision 0.087 inch (2.2mm) non-magnetic semi-rigid coaxial cable featuring silver plated copper inner conductor and silver plated copper shield throughout its construction. Unlike standard semi-rigid coax cables that use copper clad steel conductors, this cable contains zero ferrous materials. This complete elimination of magnetic materials makes it ideal for MRI systems, quantum computing cryostats, and precision instrumentation where magnetic interference cannot be tolerated. The PTFE dielectric provides 70% velocity of propagation with 29 pF/ft capacitance and 50 Ohm impedance. With 61 GHz effective frequency, >100 dB shielding effectiveness, and 173.8 dB/100ft attenuation at 50 GHz, this cable delivers reliable performance for demanding millimeter wave applications. Operating temperature range is -55°C to +125°C with full RoHS compliance.
