Epcos has released a new sample kit for its SMD CU varistors.
The electrical parameters of these CTVS (ceramic transient voltage suppression) components correspond to the leaded disk varistors of the series SIOV-S05 in case size 3225 and SIOV-S07 in case size 4032.
The varistors contained in the sample kit cover a voltage range from 16 to 385 V d.c. and are designed for surge currents of between 100 and 1200 A and a standard pulse of 8/20 μs. Depending on the type, a maximum energy of between 2200 and 23 000 mJ can be absorbed for 2 ms. The components have a maximum a.c. operating voltage exceeding 130 VRMS and thus satisfy the requirements of UL and CSA. All CU varistors in the sample kit are RoHS compatible and can be operated at temperatures of up to 85°C without derating.
In addition to the standard series for industrial and consumer electronics, the sample kit also contains special series for automotive electronics and telecommunications applications. Data sheets, application examples as well as additional information are available on an enclosed CD-ROM.
