2469 Series 5-Pin TBU® Surge Protector
The Bourns® 2469 Series Surge Protector Module incorporates Bourns® TBU® Electronic Current Limiters. Bourns® TBU® ECL devices
are electronic circuit protectors that provide high-speed overcurrent protection. The Model 2469 is designed to fail “open” should a
power cross or high current event occur.

Definitions:
Vac ..................Maximum blocking voltage for continuous AC faults; module shunts voltages greater than these ratings.
Ifault ................Maximum current-carrying capability of the module .
Vimpulse ...........Maximum protection voltage for impulse faults (Vimpulse = Ifault X Rload).
Vop ..................Maximum voltage on the input of the device that will not cause voltage limiting.
Vout .................Maximum voltage on the output of the device under any condition.
Iop ...................Maximum current through the device that will not cause current blocking (at 85 °C, use 0.80 derating factor, linear
throughout temperature range.
Iout ...................Maximum current through the device under any condition (at 85 °C, use 0.80 derating factor, linear throughout
temperature range.
tprotect .............Maximum time for the device to go from normal operating state to protected state.
ELTGS ............Each Line to Ground Simultanuously.
Line resistance
balance ............Maximum difference in series resistance for tip/ring pair (line-line).
