DC feedthrough
Description:
This series of TO package provides the mechanical foundation for mounting electronic and optical components such as semiconductors, laser diodes, sensors, and simple electronic circuits, while providing electrical signals to the packaged component through the leads for high-speed data transmission. The glass-sealed TO housings provide reliable, permanent protection of the package components from the environment and are customized to meet customer requirements.
Applications:
This series is widely used in optical communication signaling, lasers, sensors and other packages.
Features:
--Small structure
--High reliability
--Good hermeticity
Ordering Symbols:

FAQ:
What flange materials and mounting styles do you support?
- We offer various flange materials like Stainless Steel 304/316L and Titanium, supporting various mounting styles, including flange welding, threading, and brazing. Our engineering team will recommend the most cost-effective and maintainable installation based on your chamber material and hermeticity requirements.
Can multi-pin integrated feedthroughs achieve independent signal transmission?
- Yes. We can arrange dozens of independent pins within a single flange based on your needs. Our precision packaging ensures high insulation resistance and low crosstalk between pins, meeting the requirements for multi-channel sensor data transmission.
What is the temperature tolerance range of Yolanda’s insulator products?
- Our standard products typically support operating temperatures from -65°C to +250°C. For specialized high-temperature industrial applications, we can provide customized glass sealing solutions resistant to over 400°C.
