SURGE ABSORBERS

Surge protective devices(SPD)/surge absorbers are used for power line and communications systems in appliances or electronic products for the purpose of protecting against electrical surges and spikes. Mitsubishi Materials' surge absorbers are made using micro-gap technology which give them quicker and more accurate surge response characteristics.
These are broadly divided into power, communication, and ESD applications.
Surge absorbers are also called surge arresters, lightning arresters, gas discharge tubes.

Surge absorber for power line

Protection from surges on power supply lines for switching, inverter, uninterruptible (UPS), and office and home appliance power supplies, as well as photovoltaic power conditioners and inverters, EV/HEV chargers, and outdoor LED lighting.
Conform with various AC withstanding voltage tests, UL, CSA, and IEC (EN) standards

Surge absorber for communication line

Surge protection for telephone, modem, fax, VoIP, and all variants of DSL communication lines.
Capacitance of less than 1pF means it doesn't affect the signal in high speed (Mb/s) applications greatly.
