Please refer to www.unsemi.com.tw for current information.1/3 22S Series Radial Lead Varistor (MOV) General Characteristics 22S series transient surge suppressors are industrial high energy Metal-Oxide Varistors (MOVs). They are designed to provide secondary surge protection in the outdoor and service entrance environment (distribution panels) of buildings, and also in industrial applications for motor controls and power supplies used in the oil-drilling, mining, and transportation fields. The maximum peak surge current rating can reach up to 20KA (8/20μs 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 voltage (V1mA) range from 180V to 1800V Fast responding to transient over-voltage Large absorbing transient energy capability Low clamping ratio and no follow-on current Meets MSL level 1, per J-STD-020 Large absorbing transient energy capability 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 Material Operating Temperature Storage Temperature No Radioactive Material -40~85°C~125°C -40~125°C~150°C Part Numbering Varistor Voltage Tolerance: K: ±10% Type: D: Disk, S: Square Element Diameter 22 - S - XXX - K
