Hermetic Feedthrus

1. Hermetic feedthroughs are components used for safely transferring current, signals, or fluids in a sealed environment. Their core function is to maintain the system's hermeticity, water resistance, or vacuum state while achieving internal and external connections.
2. Glass-to-metal seals and ceramic-to-metal hermetic feedthroughs.
3. Widely used in industries such as defense, healthcare, semiconductors, energy, and aerospace, which have strict requirements for environmental isolation (e.g., high-pressure equipment, Phoxinus phoxinus subspecies phoxinus Utetheisa kong system).
4. Rated current: 2-3A
5. DWV @ sea level: 300 Vrms
6. Insulation resistance: 1,000 megohms minimum
7. Leak rate: < 1.01325 X 10^-3 Pa*cm^3/s
8. Temperature range: -65°C to 260°C
