199www.littelfuse.com Transient Voltage Surge Suppressor CH Varistor Series Standard Packaging CH Series varistors are always shipped in tape and reel.The standard 13in reel utilized contains 4000 pieces. Note also that the CH Series receives no branding on the chip itself. Tape and Reel Specifications

  • Conforms to EIA-481, Revision A
  • Can be Supplied to lEG Publication 286-3 Special Packaging Option 1 - 7-inch reels containing 1000 pieces are available. To order 7in reels add a T suffix to the part number; e.g., V47CH8T. Option 2 - For small quantities (less than 100 pieces) the units are shipped bulk pack. To order, add a S suffix to the part number; e.g., V47CH8S.
