Product Description
Product Overview
TO-46 metal header is a hermetically sealed package widely used in laser diode modules, optical communication devices, photodiodes, and gas sensors. The header is manufactured using a glass-to-metal sealing process that ensures excellent hermeticity, high insulation resistance, and long-term reliability.
The body is typically made of Kovar alloy, which provides a thermal expansion coefficient compatible with glass materials, ensuring a stable seal even under temperature cycling. The pins can be gold plated or nickel plated to meet different bonding and soldering requirements.
This package is suitable for applications requiring high reliability, such as aerospace electronics, optical sensors, industrial detection equipment, and medical devices.
