Introduction to Hermetic Headers: Applications and Benefits

When it comes to electronic packaging, a hermetic seal is essential for preventing contaminants from entering and damaging sensitive components. A hermetic header, also known as a hermetically sealed header, is a type of package that provides a reliable seal for electronic devices. At Hermetix, we specialize in manufacturing high-quality hermetic headers for a variety of applications. In this article, we’ll take a closer look at the benefits and applications of hermetic headers, as well as their key features and construction.

What is a Hermetic Header?

A hermetic header is a type of electronic package that provides a hermetic seal to protect sensitive components from external contaminants, such as moisture, dust, and gases. It typically consists of a metal or ceramic base with one or more electrical leads that are hermetically sealed to the base.

Benefits of Hermetic Headers

Hermetic headers offer several benefits over non-hermetic packages. For example, they provide a reliable seal against external contaminants, which helps to extend the lifespan of the electronic components. They also offer better thermal management and protection against mechanical stress and vibration.

Applications of Hermetic Headers

Hermetic headers are used in a variety of applications, including:

Medical devices: In medical devices such as pacemakers and insulin pumps, hermetic headers are used to protect the sensitive electronics from body fluids and other contaminants.

Automotive: In automotive applications, hermetic headers are used to protect electronic components from exposure to moisture, dust, and other environmental contaminants.


In summary, hermetic headers are an essential component in electronic packaging, providing a reliable seal against external contaminants and protecting sensitive components from damage.
