Product Attributes

Introduction

Littelfuse SG series gas discharge tubes deliver high surge ratings in a miniature package. Designed for SMT mounting on PCBs, they feature a compact 4.5×3.2×2.7 mm form factor. Low insertion loss makes them ideal for broadband equipment applications. Their capacitance does not vary with voltage, preventing operational issues in ADSL2+ applications where capacitance variation between Tip and Ring is undesirable. These devices are extremely robust, capable of shunting 1000A pulses without damage.
