TBFL1
Transient Limiter
The TBFL1 Transient Limiter is a protection device designed to safeguard sensitive RF measurement equipment such as spectrum analyzers and receivers from high-energy transient pulses. It allows RF signals to pass normally under standard levels but automatically limits excessive transient energy, preventing potential damage from electrostatic discharge (ESD), lightning pulses, or other high-power RF events. The unit is compact and rugged, making it ideal for both laboratory and field use where transient protection is required.
