Gas replenishment component for an enclosure
A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N 2 . The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.
