Bourns says in addition, its latest multilayer varistors offer excellent transient energy absorption due to their improved energy volume distribution and power dissipation. They feature a response time of less than 2 nanoseconds, a 50 V_rms-rated voltage with a peak pulse surge current of 4500 A and an operating temperature range of –55 to 125 ºC. Designs that can benefit from the overvoltage protection capabilities of these new varistors include radio remote units (RRU) for 5G applications, Power over Ethernet (PoE), base stations, wireless infrastructure, and measurement and control devices.
