22000µF 80V Electrolytic Capacitor – 2-Pin, 35×80mm for DIY Audio
Compact high-capacity 22000µF 80V electrolytic capacitor with 2-pin radial/axial leads and a space-saving 35×80mm body. Designed for DIY audio amplifier power supplies, filtering, and smoothing where board space or chassis depth is limited. Same massive capacitance as larger snap-in types, but in a shorter, more versatile package.
Key Features
- ✅ Capacitance: 22000µF (22000mfd)
- ✅ Voltage Rating: 80V DC
- ✅ Terminals: 2-pin (standard radial or axial lead, ± polarity)
- ✅ Body Size: 35mm diameter × 80mm height – shorter than standard 35×100mm
- ✅ Low ESR – reduced heat, cleaner power delivery
- ✅ High ripple current handling for audio amplifier duty
- ✅ Compact profile fits tighter enclosures and PCB layouts
- ✅ Brand new, factory fresh stock
- ✅ RoHS compliant

2-Pin vs 4-Pin: Which Do You Need?
- 2-Pin (this listing): Standard polarity, simpler wiring, shorter 80mm height – ideal for PCB mounting or shallow chassis where snap-in won't fit.
- 4-Pin: Dual +/- terminals for lower ESR through parallel paths – preferred when space allows and ultimate ripple performance is critical.
Both deliver 22000µF at 80V. Choose based on your mechanical constraints and wiring preference.
Applications
- DIY audio amplifier power supply filtering (Class AB, Class D)
- Preamp and headphone amplifier DC rails
- DAC and audio interface power regulation
- Active speaker amplifier plate PCBs
- Audio equipment recap / restoration projects
- Compact high-current DC power supplies
- Subwoofer plate amplifier PSU (space-constrained builds)
DIY Installation Tips
- Polarity: Observe correct +/- orientation. Reverse connection causes failure and potential venting.
- PCB Hole Size: Verify lead diameter against your board's drill holes before ordering.
- Clearance: 80mm height still requires planning – measure internal chassis depth before purchase.
- Mounting: For PCB use, consider adding cable ties or adhesive mounts for mechanical stability on vibration-prone equipment.
- Bleeder: Always include a bleeder resistor across the cap in your PSU design for safe discharge.
- Parallel: Can be paralleled with additional units for higher total capacitance and lower ESR.
Why Choose This Capacitor?
The 35×80mm 2-pin form factor solves a common DIY problem: you need the massive energy storage of 22000µF for clean bass and stable rails, but your chassis or PCB can't accommodate a 100mm-tall snap-in. This compact version gives you the same capacitance and voltage headroom in a shorter package, with standard 2-pin leads that work with any PCB layout or point-to-point wiring. A practical choice for space-conscious audio builds that don't want to compromise on power supply performance.
