2200uF 25V Aluminum Electrolytic Capacitor for Whatsminer PSU

2200uF 25V Aluminum Electrolytic Capacitor | Radial Through-Hole for Whatsminer PSU Repair

The 2200uF 25V aluminum electrolytic capacitor is a versatile through-hole component used to block direct current and pass alternating current — making it an essential bulk filter for switching power supplies and the kind of high-current low-voltage rails found in ASIC-miner PSU output stages. With its compact 13×21mm radial form factor and high 2200µF capacitance, this part is suited for use in Whatsminer switching power supplies, communication equipment, circuit boards, industrial measurement systems, automotive electronics, and similar applications.

The capacitor's rated operating voltage range of 6.3V to 25V covers most low-voltage filter positions in mining PSUs and switching converters. The ±20% capacitance tolerance meets the standard reliability spec for bulk electrolytic filters at 120Hz, 20°C. The maximum 105°C working temperature rating gives the part the thermal headroom it needs for the high-temperature interior of a continuously-running ASIC PSU — and matches the JIS-Class 1 105°C grade that mining-PSU service-life calculations assume.

Block Direct Current with the 2200uF 25V Capacitor for Efficient Circuit Performance

• 2200µF capacitance — bulk filtering capacity for switching PSU output rails.
• 6.3V to 25V rated operating voltage — covers low-voltage rails on mining PSU output stages.
• ±20% capacitance tolerance (120Hz, 20°C) — standard reliability spec for bulk electrolytic filters.
• 13×21mm compact size — space-efficient through-hole footprint, fits standard 5mm pad spacing.
• 0-85°C recommended operating temperature, 105°C maximum — JIS Class-1 grade thermal headroom.
• Aluminum electrolytic construction — proven topology for high-current bulk filtering.

Where the 2200uF 25V Capacitor Fits

The natural application is bulk filtering on the secondary-side output of a switching PSU — including Whatsminer P21 / P222 series PSU boards where these caps live in the low-voltage output filter stage. They also serve as input bulk caps on DC-DC converter modules, decoupling on power-amplifier rails, and ripple suppression on motor-drive output stages. Replace any cap that shows visible bulging, leakage, or measurable ESR drift to restore output stability — bulged bulk caps are the single most common cause of secondary-failure cascades in ageing ASIC PSUs.

FAQ — 2200µF 25V Aluminum Electrolytic Capacitor

Q: How do I know when a bulk cap needs replacing?
A: Three quick checks: (1) visual — any bulging, leaking, or rust on the cap top means immediate replacement; (2) ESR meter — if ESR has more than doubled vs spec, replace; (3) capacitance meter — if measured value drops below 80% of nominal, replace.

Q: Can I substitute a higher-voltage cap (e.g. 35V or 50V)?
A: Yes — substituting a higher-rated cap is generally fine for the voltage spec, but verify the physical dimensions still fit the original footprint (13×21mm here), and confirm the ESR / ripple-current rating is at least equal to the original.

Q: How many caps does a typical Whatsminer P-series PSU contain?
A: Usually 4-8 bulk output caps per PSU, depending on the model. Check the failed cap's part number against neighbours — they often fail in pairs.

Q: Do you ship in bulk for repair shops?
A: Yes — email contact@lys-sz.com with the quantity and we'll send a volume quote.

Q: What's the typical service life at 65°C ambient?
A: For a 105°C-rated cap operating at 65°C ambient, expected service life is approximately 5,000-10,000 hours depending on ripple-current loading. Continuous mining duty at typical PSU temperatures matches that envelope.
