Cautions and warnings
General
1. EPCOS metal oxide varistors (SIOVs) are designed for specific applications and should not be
2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs should
3. For applications of SIOVs in line-to-ground circuits based on various international and local
Storage
1. Store SIOVs only in original packaging. Do not open the package before storage.
2. Storage conditions in original packaging:
3. Avoid contamination of an SIOV’s surface during storage, handling and processing.
4. Avoid storage of SIOVs in harmful environments that can affect the function during long-term
5. The SIOV type series should be soldered within the time specified:
Handling
1. SIOVs must not be dropped.
2. Components must not be touched with bare hands. Gloves are recommended.
3. Avoid contamination of the surface of SIOV electrodes during handling, be careful of the sharp
Soldering (where applicable)
1. Use rosin-type flux or non-activated flux.
2. Insufficient preheating may cause ceramic cracks.
3. Rapid cooling by dipping in solvent is not recommended.
4. Complete removal of flux is recommended.
