Run capacitors maintain the phase shift needed to keep a motor running efficiently after startup. This capacitor is a common replacement component in HVAC equipment, installed by licensed HVAC technicians during routine service or motor replacement work. Its round form factor suits standard capacitor mounting brackets found throughout residential and light commercial equipment.\u003c\/p\u003e\n\u003cp\u003eThis capacitor is typically used in condenser fan motors and compressor circuits within split-system air conditioners, heat pumps, and packaged rooftop units. The 440-volt rating provides a safety margin over standard 370-volt applications, making it a widely accepted upgrade or direct replacement in systems where either rating is specified. Technicians commonly stock this capacitor as a high-turnover service part for warm-weather AC calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 MFD capacitance for single-phase motor run duty\u003c\/li\u003e\n  \u003cli\u003e440-volt rating compatible with both 370V and 440V specified applications\u003c\/li\u003e\n  \u003cli\u003eRound case style fits standard capacitor mounting brackets\u003c\/li\u003e\n  \u003cli\u003eContinuous-duty rated for year-round operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement run capacitor for single-phase condenser fan motors and compressor circuits in residential and light commercial HVAC systems requiring a 5 MFD, 440-volt round capacitor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eRun capacitors must be installed by a qualified HVAC technician. Disconnect and lock out all power to the unit before removing the existing capacitor, and discharge the old capacitor fully before handling terminals. Verify the MFD rating and voltage rating against the equipment nameplate before installation. Capacitors store a lethal charge and must never be handled while energized.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacitance\u003c\/strong\u003e: 5 microfarads (MFD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 440 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Style\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MOTORS AND ARMATURES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12105\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MOTORS AND ARMATURES","offers":[{"title":"Default Title","offer_id":51162174882098,"sku":"12105","price":16.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12105.jpg?v=1778891504","url":"https:\/\/voomisupply.com\/products\/motors-and-armatures-12105-run-capacitor-5-mfd-440v","provider":"Voomi Supply","version":"1.0","type":"link"}
