CG7 Series - Two Terminal Mini Gas Plasma Arresters

Littelfuse CG7 series GDT is a miniature surface mount device with a 1kA 8/20μS surge rating. Its low insertion loss and thus low off-state capacitance makes it compatible with high bandwidth applications up to the GHz RF range. This GDT’s crow barring characteristic protects sensitive ICs from surges as defined in ITU K.20/21/45 Basic and Enhanced Recommendations, GR-1089-CORE first level lightning Port Type 1 and 3, and IEC 61000- 4-5 2nd edition. It is hermetically sealed using non-radioactive materials and is thus environmentally safe. Its 2.8mm diameter size makes it the world’s smallest two-electrode single chamber GDT.

Features:

  • Up to 1kA Surge Capability in Minimal Footprint
  • Ultra-low capacitance (< 0.3 pF)
  • Surface mount form factor

Applications:

  • G.Fast Modems
  • Cable Modems
  • MoCA (Multimedia over Coax Alliance)
  • EMTA (Embedded Multimedia Terminal Adapter)
  • RF Connectors
  • xDSL
  • RJ 45 Connectors
