High Reliability Sealing Hermetic Feedthrough 50ohm RF Impedance Lightweight
- 50ohm RF impedance ensures high-quality signal transmission with minimal reflection for stable, low-loss performance
- Hermetic sealing provides a leak-proof connection, ensuring reliable operation in high-pressure, vacuum, and extreme environmental conditions
- Lightweight design reduces overall system weight, making it ideal for space-constrained applications without sacrificing performance
- High-reliability construction, designed for industries requiring robust performance in harsh environments like aerospace, defense, and medical
- Durable in extreme conditions, maintaining stable electrical and mechanical performance under temperature fluctuations, vibration, and mechanical stress
Glass to Metal Hermetic RF/DC Feedthroughs/Seals /Multi-pin Headers /Connector is also called Glass insulator. They are mainly used to transmit microwave signals, power signals and control signals between modules and modules, modules and components with gas sealing requirements. They are one of the most critical components in sealing components. The glass with low dielectric constant and low dielectric loss is used as insulating and supporting material. The housing and conductor is made of Kovar alloy that sintered under high temperature, and the surface is gold plated. The centerconductor has a variety of termination styles such as gold wire bonding, soldering and mating etc. Glass insulators are small, lightweight, hermetic, high reliable and have been widespread in electronics manufacturing industries in recent years.
Structure
Glass insulator is composed of three parts: outer conductor/shell, glass medium and center conductor/pin.Its basic structure is shown in the figure.
