By design, both capacitors are electrolytic capacitors that use an oxide-layer dielectric, but only the second model can be considered an SMD capacitor. Given their higher capacitance values and voltage compatibilities, electrolytic capacitors are generally considered through-hole capacitors.

Applications:

SMD technology, for high temperature re-flow soldering

Industrial and professional applications

Automotive, general industrial, telecom

Smoothing, filtering, buffering

Features:

1. Lightweight
2. Polarized aluminum electrolytic capacitors
3. Non-solid electrolyte
4. self healing
