Electrolytic Capacitor 47μF 25V — Radial, 105°C, Through-Hole, 10-Pack

Electrolytic Capacitor — 47μF / 25V, Radial Through-Hole (10-Pack)

A standard 47μF 25V aluminum electrolytic capacitor in radial through-hole package — rated for 105°C operation. The 47μF value is a workhorse capacitance for power supply bulk filtering, motor driver decoupling, audio amplifier supply bypassing, and Arduino/ESP32 power rail stabilization. The 25V rating is appropriate for 5V, 12V, and 15V supply rails with adequate safety margin.

Key Specifications

Capacitance	47μF
Voltage Rating	25V DC
Temperature Rating	105°C
Type	Aluminum electrolytic, radial
Polarity	Polarized (observe − stripe marking)
Lead Spacing	2.5mm (standard radial)
Compliance	RoHS compliant

Polarity — Important

Electrolytic capacitors are polarized — the negative lead is marked with a stripe on the capacitor body and is the shorter lead. Always connect the negative lead to the lower-voltage side of the circuit. Reverse polarity will damage or destroy the capacitor.

Typical Applications

• Arduino and ESP32 power rail bulk decoupling (5V supply)
• Motor driver power supply bypass (L298N, DRV8825, A4988)
• Linear voltage regulator (7805) output filter capacitor
• Audio amplifier (LM386, PAM8403) power supply bypass
• Power supply bulk filtering in transformer-based circuits
• Servo motor power rail stabilization
