Surge protector for RJ45 signal, limit voltage 40V, working temperature range from -20°C to 60°C. The FL45 features high-performance surge arresters, which feature clamping voltage and low loss over high-speed signals because of its low capacitance. In addition, the FL45 has recognized the highest quality surge protection standards IEC61000-4-5 and ITU-TK20;K21. The FL45 is designed to protect 100Base-T local and wide area communication lines.Fea..
