Round Run Capacitor 100 MFD 370 VAC
The Supco CR100X370R is a round motor run capacitor rated at 100 microfarads and 370 volts AC. It uses a drawn steel case measuring 2.375 by 4.9375 inches and carries UL and VDE approvals. Quad blade quick-connect terminals simplify wiring during installation.
HVAC motor replacements and compressor circuits
Technicians servicing air conditioning compressors, refrigeration compressors, furnace blower motors or condenser fan motors will find this part a direct replacement for Packard PRC100 and Mars 12916. It is not suited for applications requiring a different capacitance value, a higher voltage rating or a non-round case style.
100 microfarad capacitance rating
The single specification that determines fit is the 100 MFD rating with a plus or minus five percent tolerance. A system designed for a different microfarad value will not operate correctly with this capacitor.

Questions about this item
How often will the 100 MFD capacitor need replacement in continuous HVAC service?
Run capacitors like this CR100X370R are designed for years of duty; replace when capacitance drifts outside the ±5 % tolerance or the internal interrupter disconnects the element.
What is the first limit reached when the capacitor runs at full load for hours?
The operating ceiling is 185 °F (85 °C) case temperature; exceeding it triggers the physical interrupter and ends the run cycle.
How much heat does the 2.375" x 4.9375" steel case dissipate during all-day operation?
The drawn steel case and biodegradable oil are rated for continuous 370 VAC duty up to 185 °F; no forced-air cooling is specified by the manufacturer.
