The maximum peak surge current rating can reach up to 1.75KA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.  Wide operating voltages ranging from 11Vrms to 510Vrms(AC)  Fast response time of less than 25ns, instantly clamping the transient over voltage.  High surge current handling capability.  High energy absorption capability.  Low clamping voltages, providing better surge protection  Low capacitance values, providing digital switching circuitry protection.  High insulation resistance, preventing electric arching to the adjacent devices or circuits.  Transistor, Diode, IC, Thyristor or Triac semiconductor protection.  Surge protection in consumer electronics.  Surge protection in industrial electronics.  Surge protection in electronic home appliances, gas and petroleum appliances.  Relay and electromagnetic valve surge absorption.  Coating: Epoxy Resin  Lead Wire: The Copper Wire  Electrode: Silver Solder  Disk: Zinc Oxide (1) Size(mm) : 05mm to 32mm (2) Type : D: Disk, S: Square (3) Varistor Voltage : 470(47*10 0=47V) , 471 47*101=470V) (4) Tolerance : K±10%, L±15%, M±20% (5) Surge Current Standardğ J:High Surge (B: 2KV/1KA E: 4KV/2KA) surge Pulse 40times (6) Taping Mode : TR : Reel (7) Lead Form : C:Crimped, Short leg : NO : X.X (8) Coating : H:Epoxy Coating 125 Note: (5)a(6)a(7)a(8) options is non-standard  Operating Temperature: -40¥ ~ +85¥  Storage Temperature: -40¥ ~ +125¥  Working Surface Temperature: +115¥  Insulation Resistance: > 100MΩ  Coating (Epoxy Resin): Flame-Retardant to UL 94V-0  Approval Standard and File Numberğ VDEğ40046112 CQCğ16001161423 CSA&CULğE489912 07 - D - XXX - K - X - X - X - X
