Pressure-tolerant electronics
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
| Component | PTE | non-PTE |
|---|---|---|
| Connectors | All | 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 | - |
