With a robust 60,000-hour lifespan, built-in safety features, and universal compatibility, it ensures efficient motor startup and reliable operation, making it an essential upgrade for proactive HVAC maintenance. ## Description SPECIFICATIONS The capacitor is 1.78" in diameter by 3.15" in height and will run from -25 C. to +70 C. It is safety rated at 10,000 AFC. Fixes the following symptoms: As the capacitor gets older, the motor may get louder and seem to run slower. If replaced before they get weaker, it's possible to lengthen the life of the motor. Eventually, the capacitor will get too weak to start the motor and if the motor can't start, it can short out. Timely replacement of the capacitor is essential to Air Conditioning Maintenance. Safety tips for replacement: When replacing a capacitor, always be sure to turn off the power to the air conditioning unit and place a screwdriver between the terminals of the capacitor to release any stored charge. Our Capacitors are designed to be the correct fit, but it's best to measure the height and width of the capacitor to double check that the replacement unit matches the original. Count on our 20 MFD Run Capacitor for an unrivaled mix of durability, convenient functionality, and great value for money. Click ‘Add to Cart’ now!

Buy with confidence! - ✅ PART NUMBER: 20 uf or 20 MFD microfarad Run Round Capacitor. Replaces BOTH 370 VAC & 440 VAC capacitors. - ✅ FUNCTION: A 20mfd round run capacitor, combines two capacitors into one unit. It will power a compressor motor and a fan motor, and has two terminals on the top. This part works hand in hand with Electric Motors that power the compressors and condensers that make air conditioning work. For this purpose, the Capacitor works the same way as a battery. It stores and releases a large charge very quickly. This released charge gives the motor the spin it needs to start and run correctly. - ✅ EASY TO INSTALL: 20 MFD 370/440 Volts which means it will work at 370 or 440 VAC. The capacitor has advantages of low dissipation, high insulation resistance, good self-healing character, anti-striking current, strong over-carrier capacity, steady electric performance, and reliable safety with the inner anti-explosion device, etc. With a wide range of applications, this capacitor can be used for air conditioning, refrigerator, motor, and compressor. - ✅ PREMIUM QUALITY: Capacitor is 1.78’’ in diameter by 3.15’’ in height so please check this measurement carefully before purchasing. It is designed to last about 60,000 hours. It is also made from durable high quality material and well-tested by the manufacturer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B24W99D2 | | Brand | BlueStars | | Capacitance | 20 Microfarad | | Capacitance Tolerance | 5 | | Customer Reviews | 4.7 4.7 out of 5 stars (101) | | Included Components | 1 x 20 MFD uf ± 5% MFD 370/440VAC | | Item Shape | Round | | Manufacturer | BlueStars | | Manufacturer Part Number | 20uf 370-440VAC | | Material | 20 MFD 370-440VAC | | Maximum Storage Temperature | 157 Degrees Fahrenheit | | Model Number | 20uf mfd ± 5% 370-440VAC | | Mounting Type | Through-Hole Mount | | Number of Items | 1 | | Operating Voltage | 440 Volts | ## Product Details - **Brand:** BlueStars - **Capacitance:** 20 Microfarad - **Material:** 20 MFD 370-440VAC - **Maximum storage temperature:** 157 Degrees Fahrenheit - **Shape:** Round ## Images ![Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - Image 1](https://m.media-amazon.com/images/I/41kepwYfuVL.jpg) ![Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - Image 2](https://m.media-amazon.com/images/I/41IXeioIxdL.jpg) ![Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - Image 3](https://m.media-amazon.com/images/I/51yPORt87JL.jpg) ![Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - Image 4](https://m.media-amazon.com/images/I/51yPbJ8wQFL.jpg) ![Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - Image 5](https://m.media-amazon.com/images/I/51nn41ig0UL.jpg) ## Frequently Bought Together - Premium 20 MFD uf ± 5% MFD 370 V VAC or 440 Volt Multi-Purpose Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Pack of 1 - VEXUNGA AC Capacitor 45+5 uF 45/5 MFD 370 or 440 or 450 VAC CBB65B Dual Run Start Capacitors for Air Conditioner Compacitor Motor or Compressor Fan or Condenser Straight Cool - BOJACK 1 Poles FLA 30 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor --- ## 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.sg/products/496920464-premium-20-mfd-uf-5-mfd-370-v-vac-440](https://www.desertcart.sg/products/496920464-premium-20-mfd-uf-5-mfd-370-v-vac-440) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-26*
