470uF 25V Radial Electrolytic Capacitor | 10×12.5mm for Whatsminer and ASIC Hashboard Repair
The 470µF 25V radial lead electrolytic capacitor is a through-hole bulk filter cap designed for switching power supply applications — Whatsminer PSU repair, ASIC hashboard rails, LED power supplies, and other 12V-class switching converters. Low-impedance high-frequency construction with anti-solvent design for extended service life.
Physical: 10×12.5mm radial form factor. Electrical: ±20% tolerance, 105°C maximum operating temperature, 2000+ hour rated service life.
When to Replace the 470uF 25V Capacitor
- Visible bulging or leakage on the cap top — immediate replacement.
- ESR doubled vs original spec — bulk filtering degraded.
- Output rail ripple elevated on scope at the cap position.
- Service-life refresh on PSUs returning from extended duty.

FAQ — 470uF 25V Radial Capacitor
Q: Will this fit other miner brands' PSUs?
A: The 10×12.5mm radial footprint is industry-standard for 470µF/25V caps. As long as the PCB pads match 5mm lead spacing and your original cap is in the same physical envelope, this part drops in. Match the voltage rating to the original or use higher.
Q: How do I confirm a bad cap?
A: Visual check first (bulging, leakage, rust). Then ESR meter — if ESR more than doubled from spec, replace. Capacitance below 80% of nominal also indicates end-of-life.
Q: Polarity?
A: Electrolytic caps are polarized. The longer lead is positive (+). The PCB silk shows the negative terminal with a stripe / arrow. Wrong polarity = immediate failure under voltage.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com for tray-quantity pricing.
