Bourns TBU® Circuit Protection Devices
Bourns TBU® Circuit Protection Devices block transients in nanoseconds through a current-disconnecting mechanism instead of diverting or shunting the surge to ground. These high-speed surge protection components are designed to protect against faults caused by short circuits, AC power cross, induction, and lightning surges. Bourns TBU Circuit Protection Devices are resettable for full functionality after multiple fault events and ideal for telecommunications, industrial, and data communications systems.
Features
- Overvoltage and overcurrent protection in one device

- High-speed performance
- Precise output current and voltage limiting
- Exceeds Telcordia GR-1089 and ITU K.20 / K.21 requirements
- 3GHz bandwidth
- Provides automatic protection coordination
- Compact size
