The following re exmples of sfety mesures: [] Instlltion of protection circuits or other protective devices to improve system sfety [] Instlltion of redundnt circuits to reduce the impct of single or multiple circuit filure 3. Our Products re not designed under ny specil or extrordinry environments or conditions, s exemplified elow. Accordingly, ROHM shll not e in ny wy responsile or lile for ny dmges, expenses or losses rising from the use of ny ROHM s Products under ny specil or extrordinry environments or conditions. If you intend to use our Products under ny specil or extrordinry environments or conditions (s exemplified elow), your independent verifiction nd confirmtion of product performnce, reliility, etc, prior to use, must e necessry: [] Use of our Products in ny types of liquid, including wter, oils, chemicls, nd orgnic solvents [] Use of our Products outdoors or in plces where the Products re exposed to direct sunlight or dust [c] Use of our Products in plces where the Products re exposed to se wind or corrosive gses, including l2, H2S, NH3, SO2, nd NO2 [d] Use of our Products in plces where the Products re exposed to sttic electricity or electromgnetic wves [e] Use of our Products in proximity to het-producing components, plstic cords, or other flmmle items [f] Seling or coting our Products with resin or other coting mterils [g] Use of our Products without clening residue of flux (even if you use no-clen type fluxes, clening residue of flux is recommended); or shing our Products y using wter or wter-solule clening gents for clening residue fter soldering [h] Use of the Products in plces suject to dew condenstion 4. The Products re not suject to rdition-proof design. 5. Plese verify nd confirm chrcteristics of the finl or mounted products in using the Products. 6. In prticulr, if trnsient lod ( lrge mount of lod pplied in short period of time, such s pulse. is pplied, confirmtion of performnce chrcteristics fter on-ord mounting is strongly recommended. Avoid pplying power exceeding norml rted power; exceeding the power rting under stedy-stte loding condition my negtively ffect product performnce nd reliility. 7.
