Rated for both 370V and 440V operation, it features a durable copper build and operates reliably across a wide temperature range (-40°C to +85°C). With a tight ±5% capacitance tolerance and compliance with USA EIA-456-A standards, it’s a trusted choice for maintaining or upgrading legacy air conditioning systems. ## Description Product description Review: Reliable Spec Part—Returned After Fan Upgrade, Still Worth Considering for Legacy AC Systems - During a recent AC compressor overhaul, I purchased this 5µF capacitor as part of a proactive component refresh. I also installed a **dual-run capacitor** rated for both the compressor and fan circuits, anticipating the need for a separate fan capacitor alongside the new condenser fan motor. The 5µF unit arrived quickly, packaged securely with no terminal damage. The aluminum housing was solid, terminals spaced well, and the labeling was clear—ideal for quick identification during install prep. However, the fan motor I ended up installing had a **built-in capacitor**, which meant I didn’t need this standalone part. Instead, I wired the motor directly into the dual-run capacitor using the standard C, FAN, and HERM terminal layout. This worked flawlessly and simplified the system wiring. That’s the key takeaway for buyers: newer fan motors often include internal capacitors, so before sourcing a separate one, check your motor’s spec label or wiring diagram. If your system uses an older motor, this 5µF capacitor appears reliable and well-suited for run/start support. Even though it was returned unused, the build quality and delivery experience made a positive impression. If I were working on a legacy unit again—or troubleshooting a standalone fan circuit—this would be on my shortlist Review: This works good - This works good on our old AC unit ## Features - 35uf / 35MFD 370 Volt or 440 Volt Capacitor.

Your lazy start may be due to other factors and you might kick out the thermal overload or do other damage **Q: is thi capacitor will replace 370vac 70uf +/- 10% 50/60hz 70*c ?** A: You have to replaced with same size in all ways. **Q: How do you get warranty service?** A: Most capacitors are only warranted for 1 year. I suppose you would have to contact the capacitor manufacturer. **Q: MSRP 645-720 MFD CAPACITOR (Aerovox 7020) 110 vac for a drill press?** A: I only use this on my 8.5kw northern lights generator. I don't know about a drill press ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable Spec Part—Returned After Fan Upgrade, Still Worth Considering for Legacy AC Systems *by J***. on July 18, 2025* During a recent AC compressor overhaul, I purchased this 5µF capacitor as part of a proactive component refresh.
