The Supco CR45X5 is a dual run capacitor for air conditioner condenser units: 30 MFD for the compressor and 5 MFD for the fan motor in one round can. It is rated 440VAC, so it covers both 370V and 440V applications, and it uses quad blade quick-connect terminals for fast wiring. The drawn steel case and non-PCB biodegradable synthetic oil match what the major capacitor brands use. Against single-value capacitors, it saves space and wiring; against premium US-made lines, it is a budget-priced part with a shorter reputation for longevity.
