‘Varistors’
An Electronicstalk guide
Start with the news release
ESD protection devices have low dynamic resistance from
California Micro Devices, which we summarised at the time by saying "California Micro Devices has launched the CM1242-33CP, the first in a family of small outline electrostatic discharge (ESD) protection devices.".
Several months prior to that,
we featured the news release AVX develops 100pF multilayer varistor device from
AVX: "AVX Corporation has developed a 100pF version of its miniature 0201 Transguard Series multilayer varistor (MLV).".
In October 2009, we covered the news from AVX
- take a look at Ceramic varistor exhibits low leakage current
which says: "AVX has expanded its zinc oxide (ZnO) based varistor series to include an 18V-rated version that exhibits a low leakage current of 1uA maximum, which extends battery life in portable devices. ".
Take a look also at the news release from AVX, AVX offers range of application-specific varistors,
as well as Varistor provides minimal signal distortion from AVX,
and EMI filters meet surge protection standard from DEM Manufacturing.
