Fast response arrestors are designed to protect especially sensitive equipment, such as GPS receivers. Other times, fast response protection is required when the transient threat is a high-speed pulse like ESD or EMP. Fine protectors combine multiple stages of protection into a multistage arrestor design which provide excellent response and energy limitation characteristics while retaining a high Transient Current Rating in order to ensure a long lifetime. For applications where DC energy must be passed or the RF Pass Band is too low to use a quarter wavelength stub, the FPL series is an ideal “best of all worlds” solution!
