Customizable TO-5 Package Pin Configurations
Our TO-5 hermetic packages are engineered for high-reliability applications requiring superior sealing, electrical insulation, and precision pin configurations. Designed using glass-to-metal sealing technology, these packages ensure outstanding hermeticity and long-term durability under challenging environmental conditions. With customizable pin counts and lengths, this TO-5 hermetic packages can be tailored to meet the specific requirements of your microelectronic or optoelectronic design, ensuring optimal performance and compatibility.
These cylindrical headers are ideal for compact sensor assemblies, photodiodes, infrared detectors, and high-frequency components, where signal integrity and environmental sealing are paramount.

Pin length and quantity can be adapted to fit specific application needs.
The product supports flexible configuration options, including customizable pin count, lead length, and plating type (nickel, gold, or tin finishes). These options enable precise adaptation to various assembly requirements, signal integrity needs, or soldering preferences
