SMD disk varistors
24 November 2009
TDK-EPC has launched a sample kit with EPCOS SMD CU varistors.
The electrical parameters of these CTVS (ceramic transient voltage suppression) components correspond to the leaded disk varistors of the proven EPCOS 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 385V DC and are designed for surge currents of between 100 and 1200A and a standard pulse of 8/20µs. Depending on the type, a maximum energy of between 2200 and 23,000mJ can be absorbed for 2ms. The components have a maximum AC operating voltage exceeding 130V RMS 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 contains special series for automotive electronics and telecommunications applications.
