Product Overview

The SAMXON KM Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. They meet IEC60384 standards and are constructed with an aluminum case, end seal rubber, and a vinyl sleeve. These capacitors are suitable for applications requiring stable electrical parameters across a range of temperatures and frequencies, with specific attention to leakage current, capacitance tolerance, and ripple current handling. They are designed for continuous operation at rated voltage within specified temperature ranges.

Application Guidelines

Includes guidance on circuit design (operating temperature, frequency effects, common application conditions to avoid like reverse voltage, overvoltage, ripple current), using multiple capacitors in series/parallel, capacitor mounting considerations (PCB layout, hole spacing, clearance for vents), electrical isolation, product endurance, handling of date codes, and capacitor sleeve properties. Also covers capacitor handling techniques (pre-use considerations, insertion, soldering, post-solder handling, circuit board cleaning, mounting adhesives), precautions for use (environmental, electrical), emergency procedures, long-term storage, and disposal methods.
