Satellite Receiver RF Input Surge Protection Solution Products 2051-09-SM-RPLF Objective Compliance This solution is designed to offer surge protection to the RF input port from a set-top box to a satellite dish. Lightning strikes or near strikes to the building can damage the delicate RF port and the power supply which is fed to the dish. IEC 61000-4-5: SMCJ20A alone: 8/20 s surge 150 A SMLJ20A alone: 8/20 s surge 400 A SMCJ20A & 2051-09-SM & CC453232: 8/20 s surge 2 kA Solution Benefit This solution provides a low height, high current solution to exposed set-top box applications.
