Bourns

devices are high speed surge protec-

tion components designed to protect

against faults caused by short circuits,

AC power cross, induction and lightning

surges.

The TBU

provides an effective barrier behind

which sensitive electronics are not

exposed to large voltages or currents

during surge events.
