TDK-EPC, a TDK Group subsidiary, now offers detailed EPCOS SIOV Metal Oxide Varistor Specification (2011 Edition), which includes a variety of innovative products. The introduction of technical information is detailed and clear, which can help developers to choose the correct application of varistors. In addition to leaded chip varistors, various ThermoFuseTM (ETFV) and FailSafe varistors (SFS) and bulk and tape varistors are also introduced.
New additions to the specification include Q14 and Q20 varistors, whose voltage range VRMS has been extended from 320 V to 460 V. Also included is a new variant of the MP (Multipulse) series, which is not only rugged, but also extends the voltage range. The S10 model now covers the 175 V to 680 V range, while the S14 and S20 models cover the 130 V to 680 V range.
TDK-EPC has expanded the reference database of the single-chip varistors on the EPCOS website to include about 2,000 competing products. Varistors: Voltage-Resistant Resistors, also known as VDRs, are added to the competitors' ordering code. If the applied voltage exceeds the allowable value of the specific material, the varistor will become conductive. This feature makes it an ideal component for overvoltage protection applications.
