polar aluminum electrolytic capacitor Man Yue Tech ESK227M1JG16RR for electronic equipment applications

Product Overview

The SAMXON SK Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. Meeting IEC60384 standards, these capacitors offer reliable performance with a wide operating temperature range of -40C to 105C. They are constructed with a single-ended, wound element impregnated with electrolyte, enclosed in an aluminum case and sealed with end seal rubber and a PET vinyl sleeve. The SK series is suitable for general electronic applications where stable capacitance, low leakage current, and good ripple current handling are required.

Application Guidelines

Circuit Design: Considerations for operating temperature and frequency effects on electrical parameters, avoiding reverse voltage, charge/discharge applications, over voltage, and excessive ripple current. Guidance on using capacitors in series or parallel, and mounting considerations including clearance for pressure relief vents, circuit board patterns, and solder heat. Electrical isolation requirements are detailed.

Capacitor Handling Techniques: Precautions before use, insertion, manual and flow soldering, post-solder handling, circuit board cleaning, and use of mounting adhesives/coating agents. Emphasis on verifying polarity, avoiding stress on leads, and proper soldering temperatures/times.

Precautions for using capacitors: Environmental conditions to avoid (temperature extremes, water, high humidity, toxic gases, radiation, vibration/shock). Electrical precautions including avoiding touching terminals and short circuits. Emergency procedures for vent operation and electrolyte contact. Long-term storage recommendations including reconditioning.

Capacitor Disposal: Methods include incineration after crushing/puncturing or disposal as solid waste, following local laws.
