Built to rigorous USA standards and certified for 5 years of reliable service, its compact aluminum body withstands extreme temperatures from -40°C to 70°C. Featuring three terminals for fan, compressor, and common connections, it ensures efficient motor startup and operation, making it a smart, cost-saving upgrade for professional-grade HVAC maintenance. ## Description A capacitor is an electric component that temporarily stores an electrical charge. A dual "run capacitor" supports two electric motors, such as a fan motor and a compressor. Round dual run capacitors are used to start and run the unit more efficient. It saves space by combining two physical capacitors into one case. The dual capacitor has three terminals labeled "C", "FAN", and "HERM", which stand for the *C*ommon, Fan, and *HERM*etically sealed compressor.Dual capacitors come in a variety of sizes, depending on the capacitance (µF = MFD = micro farad), such as 60 plus 5 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. Same as an electric wire- 600V rated wire is better than 300V one .The capacitance(µF or MFD or micro farad) must be the same or stay within 10%+ or 5%- of its original value . Example: 70 µF cap can be substituted by 67 - 76 MFD cap with the same or better voltage ratings .If your fan is working but compressor not, 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. Review: Quick ship, easy install, works great. - This capacitor was delivered quickly, installed in minutes, and works as it should. If your AC outdoor unit is making a bunch of noise when starting up (or running), make this easy and inexpensive repair/maintenance change. Helps unit start better and run more efficiently. Review: Saved me $2,000 by buying it myself. - Three prongs make the super easy to install. This is an awesome to good to be true value for its money. It runs the capacity it claims just fine on our AC home heating unit also known as a heat pump. It's very good quality because it's outside is aluminum. It's compatible with what it says it's compatible with. If it fits your AC buy it... 😂 ## Features - 70/5 uf or 70/5 MFD Dual Run Round Capacitor. Replaces BOTH 370 & 440 VAC capacitors - Can size measures 2-1/2" diameter x 5" tall. Operating temperature range -40 C. to +70 C/ -40F to 158F - Built to the TOUGHEST USA standards for AC motor run capacitors including EIA-456-A and IEC 60252-1:2001 - GUARANTEED TO LAST 5 YEARS.

The capacitor looked exactly like the one I removed and worked great. Much cheaper than the Carrier branded one. Looks like it may be made by the same company for the OEM. ## Frequently Bought Together - PowerWell 70+5 MFD uf Micro Farad 370 or 440 Volt Dual Run Round Capacitor TP-CAP-70/5/370-440V for Condenser Straight Cool or Heat Pump Air Conditioner - Guaranteed to Last 5 Years - VEXUNGA 70/5 uF 70+5 MFD 370VAC or 440VAC Dual Run Start Round A/C Capacitor CBB65 CBB65B Air Conditioner Capacitors for AC Unit Fan Motor Start or Heat Pump or Condenser Straight Cool - BOJACK 1 Poles FLA 40 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.co.uk/products/40411626-70-5-mfd-uf-micro-farad-370-or-440-volt](https://www.desertcart.co.uk/products/40411626-70-5-mfd-uf-micro-farad-370-or-440-volt) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-13*
