1 µF, 50V (Aluminium Electrolytic), Through hole

A 1uF polarised capacitor is a common electronic component that stores electrical energy, featuring designated positive (+) and negative (-) terminals. Because it is polarised, you must connect it with the correct orientation in a DC circuit to avoid component failure, venting, or damage.

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.

The primary applications for a 1μF electrolytic capacitor include:
Audio Signal Coupling: Placed between stages of an audio amplifier, it allows musical or vocal frequencies (AC signals) to pass to the next stage while preventing unwanted DC voltage from bleeding through.
Power Supply Decoupling: Placed near active components like ICs or op-amps, it acts as a localized reservoir that absorbs high-frequency noise and sudden power fluctuations.
Timing Circuits: Used alongside resistors in RC (resistor-capacitor) circuits to create specific time delays or oscillating frequencies in timers and wave generators.
DC Blocking in Filters: Used in low-pass or high-pass active filter circuits to isolate specific frequency ranges and block DC offsets.
