1000uF 35V In-Line Electrolytic Capacitor for Whatsminer PSU repair

1000µF 35V Through-Hole Aluminum Electrolytic Capacitor | Compact 10×17mm Radial-Lead In-Line Capacitor with -40°C to +105°C Operating Range for Whatsminer Power Supply Output Filtering and Repair

The 1000µF 35V in-line electrolytic capacitor is a direct replacement for degraded output-side capacitors in Whatsminer PSUs — the small but critical component whose failure causes ripple, dropouts, and eventual PSU shutdown. Maintain reliable power delivery in your Whatsminer mining power supply by swapping aged or vented caps before they take the rest of the PSU down with them.

Compact 10×17mm radial-lead form factor fits the Whatsminer PSU output-side footprint without rework. Delivers stable filtering performance across a wide operating temperature range (-40°C to +105°C) — important for PSUs that operate near their thermal envelope inside dense farm racks. 35V voltage rating provides headroom above the typical 12-30V output rails common to mining PSU secondaries.

Typical Use in Whatsminer PSU Repair

• Output-side filter cap replacement — vented / bulged / leaking caps in PSU output filtering.
• Aging recovery — replacing caps with degraded ESR after thousands of hours of mining service.
• Pre-emptive cap rolls — replacing all output filter caps as a preventive maintenance step during PSU rebuild.
• Production assembly — refurb shops needing bulk capacitor stock for high-volume PSU rebuild lines.
• General mining PSU repair — any 10×17mm 1000µF 35V footprint in Whatsminer / similar PSU designs.

FAQ — 1000µF 35V Capacitor

Q: How do I identify a failed electrolytic cap on Whatsminer PSU?
A: Visual inspection first — look for bulged tops, brown / orange residue around the base (electrolyte leak), or vented top. Electrically: measure ESR with an ESR meter (failed caps show 10× to 100× higher ESR than spec), or measure capacitance (failed caps lose 50%+ of rated value).

Q: Can I substitute a higher-voltage cap (e.g., 50V or 63V)?
A: Higher voltage rating is always safe (the cap won't fail from over-voltage). However, the package size scales with voltage rating — verify the higher-V cap still fits the 10×17mm footprint. Capacitance value must match (1000µF).

Q: Polymer vs aluminum electrolytic — should I upgrade?
A: Polymer caps offer lower ESR and better aging characteristics but cost more and the package size differs. For OEM-spec PSU repair, aluminum electrolytic is the original choice. For mission-critical or high-thermal-stress applications, polymer is a defensible upgrade if you accept the cost and footprint considerations.

Q: Bulk pricing for PSU repair shops?
