## Overview

The HVAC YELLOW HAT 45µF round capacitor is a robust, multi-purpose replacement part designed for air conditioners operating at 370 or 440 volts. Engineered to endure extreme temperatures from -40°C to +85°C, it ensures consistent motor run performance with a tight ±5% capacitance tolerance. Compact and built to USA EIA-456-A standards, this capacitor comes with a 5-year warranty, empowering homeowners to confidently perform quick, cost-saving repairs.

## Description

Operating Temperature:-40°C to +85°C(std.) /-40℉ to 185℉.Capacitance Range: 3-120uF/Capacitance Tolerance: ±5%(std.)-others available. Operating Frequency: 50-60Hz

Review: Very good product, was easy to install and worked perfectly. Installed onto a 5 Ton Rheem unit about 10 yrs old.
Review: With our last A/C tuneup we were told that we would have to replace the capacitor soon and given a price. It was hundreds of dollars to unplug the old one and plug this one in. After watching a few videos online, I felt comfortable enough to do it on my own. Took less than 10 minutes and saved us a bundle. The product seems to be working well and standing up to the Florida heat. Save yourself the money, taking time off of work to be home for a tech, and feel good that you are able to repair something in your home yourself. This is the most common A/C repair and costs owners thousands of dollars over the lifespan of their system. Using this item, that cost drops to maybe $100 over the lifespan of your system. Cannot recommend this enough.

This part was a perfect replacement for my failed capacitor. Time will tell if it lasts but it was so cheap and It’s such an easy fix, I’m not really worried about it. If you own a home, I highly recommend you learn how to replace this capacitor. It only takes 10 minutes and it will save you hundreds of dollars, especially if you have to do more than one in your life. My AC unit is under warranty, but only the parts, not labor. So it would’ve cost me $200-$300 to get this fixed under a warranty claim. This is a much better option.
