Product Details

The Mars 12642 is a dual-section motor run capacitor rated at 65/5 MFD (microfarads) and 370/440 volts AC, housed in a round aluminum can. It delivers two capacitance values in a single unit — 65 µF for the compressor circuit (HERM terminal) and 5 µF for the condenser fan motor (FAN terminal) — making it a compact, all-in-one replacement for systems that previously used two separate capacitors.

Designed for continuous-duty operation in single-phase PSC (Permanent Split Capacitor) motor circuits, this capacitor is well-suited for residential and light commercial HVAC air conditioning condensers and heat pump systems.

Key Features:

  • Dual Capacitance: 65 µF (HERM/Compressor) and 5 µF (FAN/Fan Motor) in one round unit
  • Dual Voltage Rated: Compatible with both 370V and 440V AC systems
  • Frequency: 50/60 Hz
  • Terminal Configuration: Three-terminal (C, HERM, FAN)
  • Operating Temperature Range: -40°C to +70°C (-40°F to +158°F)
  • Construction: Metallized polypropylene film dielectric in a round aluminum case
  • Internal Protection: Pressure-sensitive interrupter for added safety
  • Non-PCB: Environmentally compliant, PCB-free construction
  • Standards: Meets EIA-456A performance standards
  • Tested and approved by major US motor and compressor manufacturers

Cross-Reference / Replaces: GE Genteq C3655, C3655R, C4655, C4655R, SUPCO CR65+5X370R, CR65+5X440R, Mars 14358, Mars 12358, and other capacitors rated 65+5 x 370 or 440 VAC.

When replacing, always match the VAC voltage rating and µF (microfarad) capacitance values to the original unit. Physical dimensions may vary between manufacturers.

Top notch business prompt on time

Start to finish everything went well.

Everything came in really quick and packed well. Apparently I just ordered the wrong part.

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

Quick and hassle free

Awesome experience! Would definitely do business with you guys again

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.

I ordered my part on a weekend and received it by Tuesday. You guys are awesome!
