10 µF, 16V (Aluminium Electrolytic)

10 µF, 16V (Aluminium Electrolytic), Through hole

Identification and Orientation
The Long Lead Rule: The positive lead (anode) is visibly longer than the negative lead on through-hole models.
The Stripe Indicator: The capacitor body features a printed stripe (usually containing a minus symbol -) marking the negative lead.

A 10µF electrolytic capacitor is a highly versatile polarized component used for DC filtering, signal decoupling, energy storage, and smoothing power supplies in electronic circuits. Because it provides moderate capacitance in a small form factor, it is a staple in both low-voltage DIY projects and industrial applications.

Common Applications
Power Supply Filtering & Smoothing: Placed across voltage regulator inputs and outputs to reduce voltage ripple and smooth rectified DC voltages.
Decoupling: Used to isolate different sections of a circuit by filtering out high-frequency AC signals and stabilizing DC lines.
Audio Signal Coupling/Bypassing: Acts in series or parallel to pass AC audio signals while blocking DC, frequently used in preamps and amplifiers.
Timing Circuits: Paired with resistors to create precise RC (resistor-capacitor) timing delays in oscillator or timer circuits.
Energy Storage: Provides a temporary reservoir of charge in circuits to handle brief, sudden demands for power.
