How do you mount an aluminum electrolytic capacitor?

Mount the capacitors with the vents up to reduce the amount of electrolyte expelled if a vent operates. Aluminum electrolytic capacitors are normally polarized and require correct-polarity installation in the circuitry. To ensure correct mounting and identification of the polarity, put a clear + and/or – on the board layout marking.

What are the characteristics of aluminum capacitors?

The essential property of a capacitor is to store electrical charge. The amount of electrical charge (Q) in the capacitor (C) is proportional to the applied voltage (U). d = thickness of the dielectric (oxide layer in aluminum capacitors) (m). Characteristics of aluminum capacitors vary with temperature, time and applied voltage.

How do you measure capacitance of aluminum electrolytic capacitors?

For aluminum electrolytic capacitors, capacitance is measured as the capacitance of the equivalent series circuit at 25 oC in a measuring bridge supplied by a 120 Hz source free of harmonics with maximum AC signal voltage of 1 Vac and no bias voltage. The capacitance varies with temperature.

What is a standard measuring frequency for aluminum capacitors?

Standard measuring frequencies for aluminum capacitors are 100 Hz or 120 Hz. DC capacitance is given by the amount of charge which is stored in the capacitor at the rated voltage (UR). DC capacitance is measured by a single discharge of the capacitor under defined conditions. Measuring procedures are described in “DIN 41328, sheet 4” (withdrawn).

How do aluminum electrolytic capacitors work?

With non-solid electrolyte aluminum electrolytic capacitors the aluminum cases connect to the negative terminals by contact with electrolyte. The resulting isolation resistance may vary from a few ohms to a few thousand ohms. For axial leaded capacitors and flatpacks the case is connected to the negative lead.

How to clean aluminum electrolytic capacitors?
