It sits on the local 18V\/24V boost rails and on the gate-driver bias domains, smoothing transients between switching events.

On a hashboard this typically shows up as one chip series losing nominal voltage, intermittent hash-rate drops, or boot loops on cold start. Visual inspection plus an ESR\/capacitance meter on a desoldered cap quickly confirms whether the part is the cause.\u003c\/p\u003e\n\u003ch3\u003eReplacement Procedure\u003c\/h3\u003e\n\u003cp\u003ePre-heat the board to 130-150°C. Remove the failed cap with hot air at 280-300°C, taking care to maintain polarity orientation. Clean the pads with flux and braid. Place the new 47uF\/50V cap with the negative stripe matching the board silkscreen. Reflow at 280°C for 8-12 seconds. After cooling, power the board on a bench supply and verify the targeted rail returns to nominal voltage with low ripple.\u003c\/p\u003e\n\u003ch4\u003eCapacitor Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCapacitance\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e47uF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eVoltage Rating\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e50V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAluminum electrolytic, SMD V-case\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eDimensions\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e6.3×7.7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eTemperature Rating\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e-40°C to +105°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eTolerance\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e±20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAntminer S19 \/ S21 \/ T21, Iceriver KS3L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Capacitors \u0026amp; Hashboard Repair Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/330uf-30v-smd-capacitor-antminer-hash-board-repair\"\u003e330uF 30V SMD Capacitor – Antminer S19+\/S21\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/220uf-16v-smd-aluminum-electrolytic-capacitor\"\u003e220uF 16V SMD Aluminum Electrolytic 6.3×7.7mm\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/450v-560uf-35-50mm-aluminum-electrolytic-capacitor-for-power-supply-unit-repair\"\u003e450V 560uF Snap-In Cap – PSU Repair\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 Hashboard\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed 47uF\/50V caps in tray quantity? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for bulk pricing.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":43834564837555,"sku":null,"price":0.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/47uF-50V-SMD-Capacitor-Replacement-Antminer-S19-S21-T21-Iceriver-KS3L-Hash-Board.webp?v=1744556263","url":"https:\/\/lys-sz.com\/products\/47uf-50v-smd-capacitor-antminer-iceriver-hashboard","provider":"LYS Shenzhen","version":"1.0","type":"link"}
