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

Failed but good customer service.
13 months old and failed. 5uf @ 440v on a 220v motor as starter cap. Capacitor failed internally and now reads 387nf. I was expecting much longer life. Update, after contacting YellowHat, they responded quickly (less than 24 hours) and replaced the unit. Great customer service.

Great run capacitor
This cap worked great to replace the run cap for the circulation pump in my Artesian hot tub. The motor would hum but not start. After checking the old cap with my meter it was almost completely dead. After installing this new one it’s working great. The new one is almost exactly 5uf too, well within the rated tolerance. Curious to see how long this lasts but at $8 I’m already satisfied. Order a spare to have on hand.

capacitor
It worked find, 5 mf. China made. It's terminals seemed a bit smaller, had to crimp connectors a bit before installing. Not a biggie.

Accurate cap
Turns out this was not my problem but I checked the item out of the box with my multi-meter. Reads, 5,03 mfd, right on the money so it is a good cap as far as accuracy
