The LL-1111-30 filter is designed to function with 48 volt communications power. The filter has excellent low frequency differential performance which will even smooth out power supply ripple transients from system switching. These ripple transients are clamped to 75 volts to protect sensitive circuitry. There is also substantial differential capacitance which will help maintain system power during battery switch-over for 5 milliseconds under 25 amp load conditions. The common mode insertion loss starts as low as 1Khz to provide the ultimate in system noise protection.
