## Overview

The Capacitor AC 45+7.5 uF is a robust dual-run start capacitor designed for AC motors, combining two capacitances (45 and 7.5 µF) in a single metal-encased unit. Rated for 370-440V AC and operating reliably between -40°C and +70°C, it supports compressor and fan motors with precision ±6% tolerance. Its compact 2-inch diameter by 4-inch height form factor and clearly labeled terminals make it an ideal, universal replacement for various HVAC and industrial motor applications.

## Description

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.  Ombines two capacitors into one unit. Three terminals on the top are labeled "Herm"/"H" for the compressor motor,  "Fan"/"F" for the fan, and "C" for the common line.It will power a compressor motor and a fan motor Model: CBB65（Universal model） Shell material: metal Dielectric Material: metallized polypropylene film Tolerance: ±6% Rated voltage: 370~440V Frequency: 50 / 60Hz Safety rated: 10,000 AFC Capacitor dimension: Diameter<1.97 inch> Height <4.53 inch> Operating temperature: -40 ℃ to +70℃ This capacitor is used for start-up and operation of AC motors with frequency of 50Hz/60Hz such as Industrial Grade Replacement for Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and Compressors.  It is small in size, lightweight, heat resisting and anti-explosion.
