MZA ALUMINUM SURFACE MOUNT NEW SERIES Engineering Bulletin Oct 03 MZA Series Surface Mount Lowest Impedance Lead-Free Construction Solvent Proof 105 C Maximum Actual Size Temperature The MZA series is United Chemi-Cons lowest impedance vertical surface mount capacitor series. These low impedance capacitors are also constructed of lead-free materials and can withstand high temperature, lead-free alloy reflow soldering. The MZA series has a wide temperature range of 55 C to 105 C with a rated lifetime of 2,000 hours at 105 C. Available in low profile case sizes ranging from 4 5.8mm to 10 10mm, the MZA series is suitable for general purpose applications where miniaturization and Pb-free requirements exist. The MZA 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.
