Product OverviewProduct Name: TO63-03A Hermetic Sealing Package
Model Number: TO63-03A
Package Type: TO-style metal can (Transistor Outline)
Sealing Technology: Glass-to-Metal Sealing (GTMS)
Materials: Housing: Kovar alloy (Fe-Ni-Co) or stainless steel Pins: Kovar, Dumet, or custom conductive materials Insulation Medium: Borosilicate or high-insulation glass
Key Features & AdvantagesExcellent hermeticity with leak rate ≤1×10⁻⁸ atm·cc/sec (helium
leak test), suitable for aerospace, defense, and high-reliability
applications Wide temperature range from -55°C to +300°C for use in extreme
environments Strong mechanical structure with high resistance to vibration and
shock Effective thermal path through the TO-style metal base, ideal for
power components and heat-sensitive devices Full customization available: pin configuration, plating thickness,
housing size, materials, etc.
