Electrolytic Capacitor Quick Guide
SMD aluminum
electrolytic capacitors are compact, polarized components commonly used for
filtering, smoothing, decoupling, and energy storage in electronic circuits.
Their markings can indicate capacitance, voltage rating, series identification,
and other manufacturer-specific information.

What the Key
Ratings Mean
Capacitance
(µF)
Indicates the
capacitor's capacitance, or its ability to store electrical charge.
Rated Voltage
(V)
The maximum
specified DC voltage the capacitor is designed to withstand under its rated
conditions.
SMD Size
SMD aluminum
electrolytic capacitors use a surface-mount construction designed for compact
PCB assembly. Manufacturer catalogs show that case dimensions and marking
conventions can vary between series.
Technical
note: The exact interpretation of markings such as series codes and voltage
codes is manufacturer- and series-dependent. I could verify the general SMD
aluminum-electrolytic capacitor characteristics from manufacturer
documentation, but I could not independently verify the exact five marking/code
breakdowns shown in this image from authoritative manufacturer documentation.
Therefore, those specific code interpretations should be treated as
reference-image information rather than a universal decoding standard.
