Low to Medium Surge GDT -- CG675SM-Image

Littelfuse CG6 series GDT is a miniature surface-mount device with a 3kA 8/20 surge rating. This ITU-T K.12 Class 1, Type 1 GDT provides protection against fast rising transients typically caused by nearby lightning events. 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, 3, and 5, and IEC 61000-4-5 2nd edition Level 5 and below. It is hermetically sealed using non-radioactive materials and is thus environmentally safe. Its 3.5mm diameter size makes it the world’s smallest two-electrode single chamber GDT available.
