Buying Guide

Match capacitance values

Choose a capacitor whose microfarad (µF) ratings match the motor and compressor requirements—common dual-run pairs include 50/7.5 µF, 45/5 µF, and 30/5 µF for many heat pumps

Verify voltage rating

Select capacitors rated for the system's operating voltage; many industrial HVAC run capacitors use 370–440V to cover typical 240V single-phase and higher-tolerance systems

Check physical form factor

Confirm the CBB65-style case, mounting type, and terminal layout fit your unit to avoid clearance or connection issues during replacement

Consider multi-pack value

Multi-packs can reduce per-unit cost and provide spares for maintenance; evaluate the cost per capacitor when comparing 3–5 pack offerings

Assess brand and specs

Use reputable suppliers and review detailed specs like tolerance, temperature rating, and expected lifespan to ensure reliable performance in heat pump applications
