Specifications

IEC61000-4-5 and ITU-TK20&K21 are the recognized standards for top quality surge protectors,

Introduction:
IEC61000-4-5 and ITU-TK20&K21 are the recognized standards for top quality surge protectors, FL-BNC made by the high response surge arresters, the advantage is allowed clamping voltage and low loss against high speed signal, because  it had a low capacitance. Designed to protect the equipment and coaxial line, connect in series. Interface accord with BNC standard.
