PRECAUTIONS & GUIDELINES
Explanation of Product

Operating and Installation Environment and Performance Limits

Designing Circuits Using Non-Solid and Solid Aluminum Electrolytic Capacitors

Precaution

1. Select capacitors
according to the operating and installation environment,
and use the capacitors
within the specified limits
and conditions specified in the product literature.

Explanatory Notes

1. Using capacitors beyond their maximum specified limits can reduce performance and cause catastrophic failure such as a short circuit, open circuit, electrolyte leakage, explosion or fire.

Review and evaluate the following conditions before selecting and installing aluminum electrolytic capacitors to avoid damage and failure.

(1) Environmental Conditions

    (a) Operating temperature range (maximum and minimum temperatures)

    (b) Storage temperature range

    (c) Exposure to toxic gasses, salt-mist, water or oil spatters

    (d) Exposure to ultraviolet rays, ozone or radiation

    (e) Exposure to heat producing elements that affect ambient temperature

(2) Electrical Conditions

    (a) DC or AC circuits or circuits with changing polarity

    (b) Maximum voltage value

    (c) Reverse voltage circuits

    (d) Frequently repeated charging and discharging cycles

    (e) Ripple currents and ripple voltages

    (f) Circuits with pulsing voltages

(3) Mechanical Conditions

    (a) Vibration

    (b) Mechanical shock

    (c) Mechanical stress (i.e., constant or repeated force)

(4) Installation Conditions

    (a) Assembly process, including the use of mounting or insertion machines

    (b) Soldering process

    (c) Cleaning process

2. If your circuit design requires capacitors with specifications and conditions not included in our product literature, please consult United Chemi-Con for assistance and recommendations.
