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
