Revised: BT.12/07/23 **3** Varistor **Datasheet** ## **Surface Mount Metal Oxide Varistor** SM10 Series ## **Reflow Soldering Profile Recommendation** ## **Wave Soldering Profile Recommendation** ## **Lead-Free Soldering Recommendations:** The terminals of SM10 series devices are tin-plated. The recommended lead-free solder paste is SAC305 (Sn96.5Ag3.0Cu0.5) with an RMA flux, though there is a wide selection of pastes and fluxes available that should be compatible. The reflow soldering profile must be constrained by the maximums in the “Lead-Free Reflow Soldering Profile”. **Note:** The Lead–free paste, flux and profile were used for evaluation purposes by Littelfuse based on industry standards and practices. There are multiple choices of all three available, so it is advised that the customer explores the optimum combination for their process as processes vary considerably from site to site. ## **Part Numbering System** ## **V 275 SM10** ## **Dimensions** **Prefix** ## **Dimensions in mm** **==> picture [287 x 285] intentionally omitted <==** **----- Start of picture text -----**
