Leaded varistors B722* SuperioR-MP, S20 series 3 Lead configuration Straight leads are standard for disk varistors. Other lead configurations as crimp style or customer-specific lead wire length according to 3.1, 3.2, 3.3 and 3.4 are optional. Crimped leads (non-standard) are differently crimped for technical reasons; the individual crimp styles are denoted by consecutive numbers (S, S2 through S5) as shown in the dimensional drawings below.

Leaded varistors B722* SuperioR-MP, S20 series Cautions and warnings General 1. EPCOS metal oxide varistors are designed for specific applications and should not be used for purposes not identified in our specifications, application notes and data books unless otherwise agreed with EPCOS during the design-in-phase. 2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs should be evaluated taking into consideration worst-case conditions. 3.
Leaded varistors B722* SuperioR-MP, S20 series Mounting 1. Potting, sealing or adhesive compounds can produce chemical reactions in the SIOV ceramic that will degrade the component’s electrical characteristics. 2. Overloading SIOVs may result in ruptured packages and expulsion of hot materials. For this reason SIOVs should be physically shielded from adjacent components. Operation 1. Use SIOVs only within the specified temperature operating range. 2.
