OVERVIEW

TO headers are a common hermetic solution to meet demands for high reliability in small microcircuit applications. A TO package has two parts: the TO header and a TO cap. The header is the base that connects the leads and provides power, while the TO cap provides environmental protection as well as additional support for the package. The hermetic seal protects the device from moisture and other contaminants. It integrates easily into circuit boards, ensuring stable and reliable performance. They come in a variety of sizes and leads to work with multiple applications
