Compact S14 AdvanceD-MP Series Varistors

TDK Corporation presents the EPCOS Compact S14 AdvanceD-MP series of metal oxide disk varistors that feature smaller dimensions with the same excellent performance as comparable S14 AdvanceD-MP types. The disk sizes of the new B72214P2 varistors range from 17 mm x 13 mm to 18 mm x 14 mm (h x w), a reduction of approximately 3 mm. Like their standard S14 counterparts, these components offer a maximum surge current capability of 6 kA at 8/20 µs, according to IEC 62368-1. The Compact S14 series covers a wide operating voltage range from 130 V_RMS to 460 V_RMS. The multiple pulse varistors are designed to be used in power supplies as the primary protection against low-level repetitive surge currents. Their optimized design results in an improved derating performance over time. All types have UL, CSA, VDE, and IEC approval.

Thanks to their compact dimensions and outstanding electrical characteristics, the Compact S14 varistors help design engineers reduce the size of their products.  These varistors are suitable for a wide range of applications including switch-mode power supplies, drivers for LED lighting, home appliances, and smart meters.
