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 50 MFD Run Capacitor for an unrivaled mix of durability, convenient functionality, and great value for money. Click ‘Add to Cart’ now!

Review: It a capacitor, it worked as a an OEM replacement for my Trane furnace Review: Perfect replacement for my 2.5 hp 12 amp Laguna bandsaw motor ## Features - ✅ PART NUMBER: PART NUMBER: 50 uf or 50 MFD microfarad Run Round Capacitor. Replaces BOTH 370 VAC & 440 VAC capacitors. - ✅ FUNCTION: 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: 50 MFD Volts which means it will work at 370 or 440 VAC. A dual run capacitor, such as this 40/5, combines two capacitors into one unit. It will power a compressor motor and a fan motor, and has three terminals on the top. They are labeled "Herm" for the compressor motor, "Fan" for the fan, and "C" for the common line. - ✅ PREMIUM QUALITY: Capacitor is 2" in diameter by 4 1/2" 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. - ✅ MONEY-BACK GUARANTEE: For any reason you're not completely satisfied, you can ask for a replacement or FULL refund, no questions asked. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B094CL1H2K | | Brand Name | BlueStars | | Capacitance | 50 Microfarad | | Customer Reviews | 4.4 4.4 out of 5 stars (38) | | Item Shape | Round | | Manufacturer | BlueStars | | Material Type | Polypropylene Polyester | | Maximum Voltage | 440 Volts | | Mounting Type | Snap-In Mount | | Operating Voltage | 440 Volts | | Upper Temperature Rating | 70 Degrees Celsius | ## Product Details - **Brand:** BlueStars - **Capacitance:** 50 Microfarad - **Material:** Polypropylene Polyester - **Operating voltage:** 440 Volts - **Shape:** Round ## Images ![50 MFD uf ± 5% MFD 370 V VAC or 440 Volt Motor Run Round Capacitor by Blue Stars - Compatible for Air Conditioner or Heat Pump Condenser - Image 1](https://m.media-amazon.com/images/I/71zRl7ATjQL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***N on 19 November 2025* It a capacitor, it worked as a an OEM replacement for my Trane furnace ### ⭐⭐⭐⭐⭐ Review *by R***Y on 28 July 2025* Perfect replacement for my 2.5 hp 12 amp Laguna bandsaw motor ### ⭐⭐⭐⭐⭐ Review *by M***K on 4 June 2023* So far so good. Had 2 of the yellow hat capacitors fail in under 1 year so hopefully this one holds up better to the Phoenix heat. This unit is slight taller than other units of similar specs but it still fit and I am hopeful that difference is due to build quality. --- ## 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.is/products/550043746-50-mfd-uf-5-mfd-370-v-vac-or-440](https://www.desertcart.is/products/550043746-50-mfd-uf-5-mfd-370-v-vac-or-440) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-15*
