MKA ALUMINUM SURFACE MOUNT UPGRADE Engineering Bulletin Oct 03 MKA Series Surface Mount Lead-Free High Temperature Reflow Soldering Vertical Chip Solvent Proof 105 C Maximum Actual Size Temperature The MKA series is a vertical chip capacitor series from United Chemi-Con designed for lead-free, high temperature reflow soldering. The heavy-duty external materials and special reformulated electrolyte enhance the durability of MKA capacitors to withstand lead-free alloy melting points of 210 C to 230 C during the soldering process. These MKA series capacitors are available in six voltage ratings and have a rated lifetime of 1,000 to 2,000 hours at 105 C depending on case size. The MKA series capacitors are solvent proof. Refer to the Mini-Glossary for cleaning guidelines and recommended cleaning agents that are compatible with United Chemi-Con products. Summary of Specifications Surface mount terminals.
