This document provides guidelines for the proper use and handling of Aluminum Electrolytic Capacitors to ensure optimal performance and extended lifespan. It covers essential precautions regarding polarity, voltage, ripple current, operating temperature, frequency, storage, installation, and soldering.

1. Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors if polarity is uncertain. DC electrolytic capacitors are not suitable for AC applications.
2. Bipolar Capacitors: Suitable for pulse and polarity reverse circuits, but not for pure AC or high ripple current circuits.
3. Operating Voltage: Do not exceed the rated voltage. Recommended working voltage is 70-80% of the rated voltage for extended life.
4. Ripple Current: Do not allow ripple current to exceed permissible limits to prevent overheating, capacitance reduction, and damage. Generally, do not exceed 80% of the rated current.
5. Charge/Discharge Circuits: For circuits with rapid charge and discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise.
6. Operating Temperature: Capacitor characteristics vary with temperature. Lower temperatures generally ensure longer life.
7. Temperature and Life Relationship: Capacitor life is related to operating temperature. A 10 reduction in temperature can double the lifespan at rated temperature. The formula for calculating life is provided.
8. Operating Frequency: Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to higher ambient temperatures.
9. Storage and Treatment: For capacitors stored for a long time, leakage current may increase and withstand voltage may decrease. Before use, gradually apply DC voltage up to the rated voltage.
10. Case Insulation: The capacitor case is not insulated from the cathode terminal. If case insulation is required, implement insulation measures at the mounting point.
11. Force on Terminals/Leads: Avoid applying excessive force to terminals and leads to prevent breakage, separation, or internal connection failure.
12. Bending Leads: When bending leads for horizontal mounting, maintain a 2mm safety distance from the capacitor body to prevent internal structural damage.
13. Circuit Board Cleaning: Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents.
14. Soldering: Keep soldering irons away from plastic sleeves. For solder dipping, maintain temperature within 260 and duration not exceeding 10 seconds to prevent damage.
15. Hole Layout on PCB: Ensure mounting hole spacing equals lead spacing to avoid stress on leads. Carefully consider hole layout to prevent solder splashing onto the capacitor body.
