Capacitors work like batteries on start-up of the motor where extra electrical energy assists the unit in overcoming the latency of the motor to start. Capacitors charge at different times depending on capacity. Typically it uses 5 time constants for a capacitor to charge and discharge. All this means that a small cap will charge faster than a large one but means little to the user if they are not using it as some part of a timing circuit. The Booster Supco Cap adds extra energy on startup so the unit gets that extra electrical push. This is a very simplified answer to a somewhat lengthy Study of CAPs in EE courses and how they are used and work. **Q: Where do I buy the wires to hook it up? I can't splice on the terminals myself** A: The wires are already on the condenser unit... If you have a separate capacitor for fan don't use that terminal or vice versa **Q: would this fit C3455R?Thanks** A: No. PowerWell 45+5 is 2 3/8” Genteq C3455R is 2” **Q: Dose it fit trane xl16i 4ttx6048?** A: If your your system issue is the compressor does not start once called and the fan does the you have a capacitor problem. Validate the capacitance in your system; 45uf for the compressor and 5uf for the fan then this product will work. The strap and connector is standard. ## Frequently Bought Together - PowerWell 45+5 MFD 45/5 uf 370 or 440 Volt Dual Run Round Capacitor PW-45/5/R for Condenser Straight Cool or Heat Pump Air Conditioner - Guaranteed to Last 5 Years - BOJACK 1 Poles FLA 30 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor - VEXUNGA AC Capacitor 45+5 uF 45/5 MFD 370 or 440 or 450 VAC CBB65B Dual Run Start Capacitors for Air Conditioner Compacitor Motor or Compressor Fan or Condenser Straight Cool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/42420079-45-5-mfd-45-5-uf-370-or-440-volt](https://www.desertcart.be/products/42420079-45-5-mfd-45-5-uf-370-or-440-volt) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-15*
