The \u003cstrong\u003e±20% capacitance tolerance\u003c\/strong\u003e meets the standard reliability spec for bulk electrolytic filters at 120Hz, 20°C. The maximum \u003cstrong\u003e105°C working temperature\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch3\u003eBlock Direct Current with the 2200uF 25V Capacitor for Efficient Circuit Performance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2200µF capacitance\u003c\/strong\u003e — bulk filtering capacity for switching PSU output rails.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.3V to 25V rated operating voltage\u003c\/strong\u003e — covers low-voltage rails on mining PSU output stages.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±20% capacitance tolerance\u003c\/strong\u003e (120Hz, 20°C) — standard reliability spec for bulk electrolytic filters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13×21mm compact size\u003c\/strong\u003e — space-efficient through-hole footprint, fits standard 5mm pad spacing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0-85°C recommended operating temperature\u003c\/strong\u003e, \u003cstrong\u003e105°C maximum\u003c\/strong\u003e — JIS Class-1 grade thermal headroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum electrolytic construction\u003c\/strong\u003e — proven topology for high-current bulk filtering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere the 2200uF 25V Capacitor Fits\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003e2200uF 25V Aluminum Electrolytic Capacitor Features\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitance\u003c\/td\u003e\n\u003ctd\u003e2200µF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Operating Voltage\u003c\/td\u003e\n\u003ctd\u003e6.3V to 25V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitance Tolerance\u003c\/td\u003e\n\u003ctd\u003e±20% (120Hz, 20°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitor Size\u003c\/td\u003e\n\u003ctd\u003e13×21mm (radial through-hole)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Operating Temperature\u003c\/td\u003e\n\u003ctd\u003e0-85°C (185°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Working Temperature\u003c\/td\u003e\n\u003ctd\u003e105°C (221°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eAluminum Electrolytic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eFAQ — 2200µF 25V Aluminum Electrolytic Capacitor\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I know when a bulk cap needs replacing?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I substitute a higher-voltage cap (e.g. 35V or 50V)?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many caps does a typical Whatsminer P-series PSU contain?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do you ship in bulk for repair shops?\u003c\/strong\u003e\u003cbr\u003eA: Yes — email contact@lys-sz.com with the quantity and we'll send a volume quote.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What's the typical service life at 65°C ambient?\u003c\/strong\u003e\u003cbr\u003eA: 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.\u003c\/p\u003e\n\u003ch3\u003eRelated products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/2200uf-16v-radial-electrolytic-capacitor-whatsminer-power-supply-repair\"\u003e2200µF 16V Radial Electrolytic Capacitor (Whatsminer PSU)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/220uf-16v-smd-aluminum-electrolytic-capacitor\"\u003e220µF 16V SMD Aluminum Electrolytic Capacitor\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/g337-2v-t520v337m004ate012-tantalum-electrolytic-capacitor-for-antminer-hash-board\"\u003eG337 2V Tantalum Capacitor (Antminer \/ Iceriver Hashboard)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-c19-16a-power-socket-250v-connector-psu\"\u003eWhatsminer C19 16A Power Socket (P21\/P222 PSU)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRepair benches stocking 2200µF 25V caps for Whatsminer PSU rebuilds in volume?
