Pressure-tolerant electronics
Appearance
Pressure-tolerant electronics (PTE) are electronic components or assemblies that can operate satisfactorily under high pressure (hyperbaric or hydrostatic, such as oil baths), without the need of a high pressure enclosure.[1]

Typical uses include submarines and oil wells.
Components
[edit]Component | PTE | non-PTE |
---|---|---|
Connectors | Alle | None |
Resistors | Carbon film, metal film, wire wound, tin oxide | Carbon comp. |
Capacitors | Ceramic, film, solid tantalum | Aluminum electrolytic, wet-slug tantalum, paper |
Relays and contactors | Open (operation is significantly slower) | Sealed |
Semiconductors | Epoxy enclosed | Metal can |
Crystals | - | Surface mount or metal can |
Resonators | Surface mount or epoxy coated | - |
