Compact, high-performance disk varistors

TDK Corporation announced the EPCOS Compact S14 AdvanceD-MP series of metal oxide disk varistors that feature smaller dimensions with the same performance as the EPCOS S14 AdvanceD-MP standard series. The disk diameters of the new B72214P2* varistors range from 13mm to 14mm, a reduction of approximately 3mm. Like the standard S14 series, these components offer a maximum surge current capability of 6kA at 8/20  µs according to IEC 62368-1. The Compact S14 series covers a wide operating voltage range from 130 to 460VRMS. The multiple pulse varistors are designed to be used in power supplies as the primary protection against low-level repetitive surge currents. The optimized design results in an improved derating performance over time. All types have UL, CSA, VDE and IEC approval. Due to compact dimensions and electrical characteristics, the Compact S14 varistors help design engineers reduce the size of products and are suitable for a wide range of applications. These include switch-mode power supplies, drivers for LED lighting, home appliances, and smart meters.
