DESCRIPTION
The SMP100LC-x x x seri es is a very low
capac itance transient surge arrest or designed
for the protec tion of high debit rate
commun i c at ion equipment. It s low capac i t ance
avoid any dist orsion of t he signal. It can also
BENEFITS
n No ageing and no noise
n Short circuit in failure mode, thus still ensuring
protection
n Board space saving
