Thunderline 50s are the world’s largest variety of RF feedthrus in the industry, with pin diameters from 0.005 to 0.040 and frequency ranges from 3 to 125 GHz. High quality levels are achieved through tight control of tolerances and the manufacturing process to yield a minimal meniscus. This minimal meniscus allows for higher frequency response while maintaining a metal-to-metal contact with the housing to achieve optimal power transfer. Even tighter meniscus of zero to below can be requested for further performance enhancement. Click on "Fast Quote" to request price and delivery.
