X-CON UER Series Conductive Polymer Aluminum Solid Capacitors

Product Overview
The X-CON UER series conductive polymer aluminum solid capacitors are designed for use in electronic equipment. These capacitors offer reliable performance with a focus on stability and longevity. Key applications include general electronic circuits where stable capacitance, low ESR, and controlled leakage current are critical. The UER series is built with a robust construction featuring aluminum foil, polymer electrolyte, and an aluminum case, ensuring durability and consistent operation across a wide temperature range.

Technical Specifications

Application Guideline Notes:

• Prohibited Circuits: Time constant, coupling, high impedance voltage retention, and circuits greatly affected by leakage current.
• Voltage: Applied voltage (including ripple peak) must not exceed rated voltage. Avoid reverse voltage exceeding 10% of rated voltage.
• Sudden Charge/Discharge: Use protection circuits if rush current exceeds 10A or 10 times the allowable ripple current.
• Ripple Current: Operate within stipulated limits to prevent self-heating and short circuits.
• Leakage Current: Self-correction mechanism may reduce increased leakage current after voltage application.
• Failure Mode: Primarily open mode (wear-out) at high temperatures; minor short circuits due to overvoltage.
• Capacitor Insulation: Marking sleeve insulation not guaranteed. Ensure separation between case, negative lead, positive lead, and PCB patterns.
• Usage Environments: Avoid direct contact with salt water/oil, direct sunlight, high temperature/humidity, chemically active gases, acid/alkaline environments, high-frequency induction, excessive vibration/shock.

Mounting Precautions:

• Do not reuse X-CON capacitors that have been stored for extended periods, dropped, or used previously.
• Ensure proper polarity, capacitance, and rated voltage selection.
• Match lead terminal pitch to PCB.
• Avoid stress on lead terminals and capacitor body during mounting.
• Soldering temperature and duration must meet specifications; avoid touching the capacitor body with the soldering iron.
• Do not submerge the capacitor body in molten solder during flow soldering.
• After mounting, do not tilt, bend, or twist the capacitor. Prevent other objects from touching it.
• When washing PCBs, use appropriate cleaning agents and limit immersion/ultrasonic time and temperature. Dry with hot air below maximum operating temperature.
