H2 Getters

Hydrogen (H2) Getters

Although pre-baking a hermetic package may prevent some outgassing, hydrogen may still be released over time.

As a result, Hi-Rel has developed hydrogen getter solutions to address this issue in several different formats for multiple product applications and industries. Hi-Rel’s offerings are detailed below, but if you have a unique requirement – please let us know. We work very closely with our customers to develop bespoke solutions.
