Product Description

TO headers (TO package headers) are precision metal packages used for mounting semiconductor devices, laser diodes, and sensor modules that require hermetic sealing.

The metal body is typically made of Kovar alloy, stainless steel, or copper alloy, providing excellent mechanical strength and thermal stability. Glass-to-metal sealing ensures a reliable hermetic structure, protecting components from moisture, dust, and environmental contamination.

Our TO headers are fully customizable, including the number of leads, dimensions, plating type, and packaging, to meet specific device requirements.
