Surface Mount Conductive Polymer Aluminum Solid Electrolytic Capacitors A767 105°C Installing Conductive polymer aluminum solid electrolytic capacitors are prone to a change in leakage current due to thermal stress during soldering. The leakage current may increase after soldering or reflow soldering. Therefore, verify the suitability for use in circuits sensitive to leakage current. A general principle is that lower temperature operation results in a longer, useful life of the capacitor.

Surface Mount Conductive Polymer Aluminum Solid Electrolytic Capacitors A767 105°C Construction Data The manufacturing process begins with the anode foil being electrochemically etched to increase the surface area and then ‘formed’ to produce the aluminum oxide layer. Both the anode and cathode foils are then interleaved with absorbent paper and wound into a cylinder. During the winding process, aluminum tabs are attached to each foil to provide the electrical contact.

Surface Mount Conductive Polymer Aluminum Solid Electrolytic Capacitors A767 105°C Product Safety cont'd 4. Unsafe Use Most failures are of a passive nature and do not represent a safety hazard. A hazard may, however, arise if this failure causes a dangerous malfunction of the equipment in which the capacitor is employed. Circuits should be designed to fail safe under the normal modes of failure. The usual failure mode is an increase in leakage current or short circuit.
