A "run capacitor" is used to boost the starting torque and efficiency on electric motors or compressor.Round capacitors come in a variety of sizes, depending on the capacitance (µF = MFD = micro farad), such as 50 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 440 volt. It will work for a while and will fail prematurely, as exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out. It is like a Ferrari that can do 440 miles per hour, driving on a road that have speed limit of 370 m/h. The capacitance(µF or MFD or micro farad) must be the same or stay within 10%+ or 5%- of its original value . Example: 50 µF cap can be substituted by 48 - 55 MFD with the same or better voltage ratings capacitor.If your motor or fan is not able to start, or the capacitor is bulged on top most likely your capacitor is defective. Round capacitor can be used to substitute oval shape one with the same MFD AND Volt specs.You will ask “Why I need a Cap that is rated 440V in my A/C?”Answer: You need to realize that a motor is an inductive device. When the supply voltage is applied to the motor run winding, the voltage across the start winding will be increased to a higher voltage value. A motor acts like a transformer with the run winding acting as the primary and the start winding acting as the secondary. This is why the capacitor has a much higher voltage rating than the 230 being the supply voltage.If a Capacitor is not EIA-456-A approved means it is NOT approved for USA market. ## Features - 50 uf or 50 MFD micro farad Run Round Capacitor .

My air compressor tripped my circuit breaker whenever I tried to turn it on. Turns out it was a bad starter capacitor inside the air compressor. No issues since I replaced it and it's been running strong.Pictures are from the old cap I replaced. This cap was an exact match. ### ⭐⭐⭐⭐⭐ Runs Great *by C***Y on June 8, 2025* Awesome & corrected the issue. Running great since 2019! ### ⭐⭐⭐⭐⭐ Worked for me. *by C***P on June 1, 2025* Bought this for my pool pump. Saved me 200 for a new pump. ## Frequently Bought Together - PowerWell 50 MFD uf Motor Run Round Capacitor 370 V VAC or 440 Volt 50 Micro Farad PW-50/R - Guaranteed to Last 5 Years - Upgraded Version 233-280 mfd 220-250VAC ±20% Volts Round Motor Start Capacitor 50/60 Hz AC Electric Replacement Part by Blue Stars - VEXUNGA 50uF 50 MFD 370VAC 440VAC 450VAC 50/60Hz CBB65 CBB65B Run Start Capacitor for AC Unit Fan Motor Start or Pool Pump or Air Condenser Straight Cool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/43867619-50-mfd-uf-motor-run-round-capacitor-370-v-vac](https://www.desertcart.fr/products/43867619-50-mfd-uf-motor-run-round-capacitor-370-v-vac) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-09-18*
