Product Overview

The SAMXON RD Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. Meeting IEC60384 standards, these capacitors are constructed with a single-ended, wound element impregnated with electrolyte and enclosed in an aluminum case, sealed with end seal rubber and finished with a vinyl sleeve. They are suitable for a wide operating temperature range and offer reliable performance with features like safety vents for larger diameters.

Environment-related Substances

Refer to the latest document of Environment-related Substances standard (WI-HSPM-QA-072) for controlled substances.

Application Guidelines

Includes considerations for circuit design (operating temperature, frequency, life expectancy, common application conditions to avoid like reverse voltage, over voltage, ripple current), series/parallel capacitor usage, mounting considerations (circuit boards, hole positioning, pressure relief vents), electrical isolation, product endurance, date code sampling, and capacitor sleeves.

Capacitor Handling Techniques

Provides guidance on considerations before using (finite life, transient recovery voltage, leakage current increase with storage, mechanical damage), insertion (polarity, hole spacing, lead clinching), manual soldering, flow soldering, other soldering considerations, handling after solder, circuit board cleaning (solvent compatibility, drying), mounting adhesives, and coating agents.

Precautions for Using Capacitors

Details environmental conditions to avoid (temperature extremes, water, high humidity, toxic gases, radiation, vibration/shock) and electrical precautions (electric shock, short circuits).

Emergency Procedures

Instructions for handling pressure relief vent operation (turn off equipment, disconnect power) and contact with escaping electrolyte (eye flush, gargle, wash skin).

Long Term Storage

Reconditioning procedure for capacitors stored for over one year (applying rated voltage in series with a 1000 resistor for 30 minutes). Products with date codes over eighteen months require confirmation.

Capacitor Disposal

Recommended disposal methods include incineration after crushing or puncturing, or disposal as solid waste, adhering to local laws. Incineration at high temperatures is advised to prevent toxic gas release.
