Overview

KEMET’s A758 Single-Ended Conductive Polymer Aluminum

Solid Electrolytic Capacitors offer longer life and greater

stability across a wide range of temperatures. The A758

highly conductive solid polymer electrolyte eliminates the

risk of explosion from drying out and due to its low ESR

properties, is able to withstand higher ripple currents during

normal operation. The A758 is ideally suited for industrial

and commercial applications.

Applications

Typical applications include mobile phone chargers,

adapters (laptop power supplies) and medical equipment.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors A758 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.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors A758 105°C Construction Data Foil tabs Anode foil 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.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors A758 105°C Product Safety THESE NOTES SHOULD BE READ IN CONJUNCTION WITH THE PRODUCT DATA SHEET. FAILURE TO OBSERVE THE RATINGS AND THE INFORMATION ON THIS SHEET MAY RESULT IN A SAFETY HAZARD. Warning When potential lethal voltages e.g. 30 VAC (RMS) or 60 VDC are applied to the terminals of this product, the use of a hazard warning label is recommended. 1.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors A758 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.
