DF Limit for 6.3 and 10 volts is 5.0%. DF for 16 volt is 3.5%. Soldering Process The 1206 components are suitable for reflow and wave soldering. All parts incorporate the standard KEMET barrier layer of pure nickel, with an overplate of pure tin to provide excellent solderability as well as resistance to leaching. Marking These chips are normally supplied unmarked. If required, they can be laser marked as an extra cost option. More detail on the marking format is included in our Surface Mount Catalog F3102. In general, the information in the KEMET Surface Mount catalog F3102 applies to these capacitors. The information in this bulletin supplements that in the catalog. © KEMET Electronics Corporation • P.O. Box 5928 • Greenville, SC 29606 • (864) 963-6300 • www.kemet.com
