Hermetic SMP / SMPM RF Feedthroughs
PH08631-0000 and PH08632-0000 - Hermetically Sealed
RF feedthroughs for applications including hermetic microwave transceivers and sealed RF sensor packages.
Hermetron’s Hermetic SMP / SMPM RF Feedthroughs use glass-to-metal sealing with Kovar bodies and pins. Available in SMP and SMPM formats for hermetic microwave transceivers, sealed RF sensor packages and other RF assemblies.
Final suitability and operating limits are confirmed against the customer’s application requirements.
Precision hermetic RF feedthroughs in SMP and SMPM formats, engineered for high-frequency, space-constrained applications. Constructed entirely from Kovar (both body and pins), these components offer unmatched hermetic sealing, thermal stability, and RF performance for mission-critical systems.
