Varistor series minimizes leakage current

Thu, 10/01/2009 - 12:53pm

ec911pc247-webAn 18V-rated version of a Zinc Oxide (ZnO) based varistor series from AVX exhibits a low leakage current of 1 µA maximum, purportedly extending battery life in portable devices. The UltraGuard series features non-linear, bi-directional voltage-current characteristics similar to back-to-back zener diodes with an EMC (electromagnetic compatibility) capacitor in parallel. The Series also includes multistrike capabilities and will survive 1000 strikes at 15 kV contact ESD. Low and high capacitance versions are offered ranging from 40 pF through to 3000 pF. From $0.11 each in quantities of 10k.
