UT-020-SS .020" OD Stainless Steel Outer Jacket Cryogenic Coax Cable

UT-020-SS
Stainless steel 50 ohm semi-rigid cables are designed for applications where low thermal heat transfer is required such as cryogenic feed cables. Because these cables also utilize a solid PTFE dielectric, they are often the first choice for highly corrosive environments.
