UL-Rated CTVS Varistors

TDK UL-Rated CTVS Varistors withstand extensive surge and overvoltage tests and have UL 1449 approval (UL file E481997) for surge protective devices. These products enable protection against severe transient overvoltage and high surge currents, including 8/20μs pulses with peak currents up to 6kA and 10/700μs pulses up to 45A. This high surge series is predominantly used in industrial applications such as the Internet of Things (IoT), Industry 4.0, automation, production and control, and protection switches. TDK UL-Rated CTVS Varistors are also used in smart home and safety applications (fire alarms, access control, and monitoring systems) as well as in telecommunications applications, including base stations, Power over Ethernet (PoE), and IP cameras.
