Overview

The KEMET ALS70/71 high capacitance voltage (CV) screw

terminal capacitors offer tremendous performance and

reliability in a wide range of case sizes and voltage ratings,

featuring high ripple currents and a long life performance.

Volumetric eciency ensures the maximum capacitance

capability in a smaller size. They are ideally suited for

industrial and commercial applications, demanding high

reliability and long life expectancy such as frequency

converters, uninterruptible power supply (UPS) systems

and switch mode power supplies (SMPS).

Applications

Typical applications for KEMET's ALS70/71 series

of capacitors include alternative energy, smoothing,

energy storage or pulse operation, in telecommunication

demanding power supplies, process control, AC motor

control, traction, welding, and measuring.

Screw Terminal Aluminum Electrolytic Capacitors – ALS70/71, High CV, +85°C Shelf Life The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however, the leakage current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See sectional specification under each product series for specific data.

Screw Terminal Aluminum Electrolytic Capacitors – ALS70/71, High CV, +85°C MTBF The mean time between failures (MTBF) is simply the inverse of the failure rate. MTBF= 1/λ Failure Rate early failures wear out operational life Time The failure rate is derived from our periodic test results. The failure rate (λR) is, therefore, only given at test temperature for life tests. An estimation is also given at 40°C.

Screw Terminal Aluminum Electrolytic Capacitors – ALS70/71, High CV, +85°C Mechanical Data Polarity and Reversed Voltage Aluminium Electrolytic capacitors manufactured for the use in DC applications contain an anode foil and a cathode foil. As such, they are polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil.

Screw Terminal Aluminum Electrolytic Capacitors – ALS70/71, High CV, +85°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.
