surge absorbers
features
•
Surge absorber elements in discharge
tube with a microgap
•
The small size requires less board space
•
No need to distinguish polarity
•
Quick response to surge voltage
•
Stable against repeated surges
•
Available for high frequency circuits due
to the low-electrostatic capacitance
•
Marking: Color code
•
Products meet EU RoHS requirements
