TDK Corporation has released the new EPCOS B72314S2* series (AdvanceD S14 Compact) of leaded disk varistors. The series offers a wide operating voltage ranging from 175VRMS to 625VRMS. The maximum surge current capability of a single pulse current (8/20µs) is up to 6000A. Furthermore, they provide a multiple surge current capability of 3000A at 8/20µs according to UL 1449, 4th edition, type 5 listed.
The smaller dimensions with the same exceptional performance as comparable S14 AdvanceD types are especially meaningful. The disk diameters range from 13mm to 14mm, a reduction of approximately 3mm compared to AdvanceD S14 series. The coating of the disks comprises a flame-retardant synthetic resin according to UL 94 V-0. The SIOV varistors are certified according to UL, CSA, VDE and IEC.
Thanks to the compact dimensions design and excellent electrical characteristics, the types enable space-saving designs for applications, including household appliances, smart meters, inverters and many others.
