Pin/Solder Tag/Audio Aluminum Electrolytic Capacitors
ALC10S Series, +85°C
Overview
Applications
Modern electrolytic capacitors are designed for use in
power supplies, thus, most aspects of their design have
been optimized for this application. Some advances in
design may not be beneficial in audio applications where the
requirements of the capacitors are very different.
KEMET has produced the ALC10S Series of slit foil
capacitors specifically for audio applications. Its patented
design eliminates circulating currents in the aluminium
foils. This spurious current flow on the capacitor plates is
known to occur but not apparent in most applications.
KEMET's ALC10S Series of capacitors features
improvements in general construction of the capacitors
to achieve better results in audio, where fidelity of the
waveshape is very important. Great attention has been paid
to the construction details that can affect performance such
as foil type, its connections and mechanical construction.
Details of capacitance and case sizes are available in
KEMET's slit foil capacitor range.

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.
Re-age (Reforming) Procedure
Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen
to a steady value below the specified limit. During re-aging a maximum charging current of twice the specified leakage
current or 5 mA (whichever is greater) is suggested.
Environmental Compliance
As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental
effects of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like
China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic
equipment. All products in this catalog are produced to help our customers’ obligations to guarantee their products and fulfill
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulfill the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will
closely follow any changes in legislation world wide and makes any necessary changes in its products, whenever needed.
Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode
coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels
for RoHS compatible capacitors.
Because of customer requirements, there may appear additional markings such as LF = Lead Free or LFW = Lead Free Wires
on the label.

Mechanical Data
Polarity and Reversed Voltage
Aluminium Electrolytic capacitors manufactured for 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. If this were
to be reversed then the electrolytic process that took place in forming the oxide layer on the anode would be recreated in
trying to form an oxide layer on the cathode. In forming the cathode foil in this way, heat would be generated and gas given
off within the capacitor, usually leading to catastrophic failure.
The cathode foil already possesses a thin stabilized oxide layer. This thin oxide layer is equivalent to a forming voltage
of approximately 2 V. As a result, the capacitor can withstand a voltage reversal of up to 2 V for short periods. Above this
voltage, the formation process will commence. Aluminium Electrolytic capacitors can also be manufactured for use in
intermittent AC applications by using two anode foils in place of one anode and one cathode.
Mounting Position
The capacitor can be mounted upright or inclined to a horizontal position.
Insulating Resistance
≥ 100 MΩ at 100 VDC across insulating sleeve.
Voltage Proof
≥ 2,500 VDC across insulating sleeve.
Safety Vent
A safety vent for overpressure is featured on either the base (opposing end to the terminals) or the side of the can. This
appears in the form of a grooved section on the surface of the can, which is a weakened area and designed to relieve build-
up of internal pressure due to overstress or catastrophic failure.
