DESCRIPTION QUICK REFERENCE DATA
The varistors consist of a disc of low-ß ceramic material with
PARAMETER VALUE UNIT
two solid copper leads (US20 types only) or copper clad Maximum continuous voltage in operating temperature range: steel wire. The wires have a matte tin plating. They are RMS 115 to 680 V coated with UL94-V0 approved silicone lacquer, which DC 150 to 895 V provides electrical, mechanical and climatic protection. Maximum non-repetitive transient 1800 to 13 000 A current INRP (8 x 20 μs)
MOUNTING
Maximum energy  19 to 720 J The varistors are suitable for hand-mounting (bulk) or (10/1000 μs) automatic pick and place mounting (T and R). The parts can Detailed specification Based on be connected by wave soldering and pin-in-paste reflow IEC 61051-1 IEC 61051-2 soldering under defined process conditions. Bending of the IEC 61051-2-2 leads for different angle placement is not recommended. Storage temperature -40 to +150 °C
