SOTUBX 35+5 MFD Dual Run Capacitor vs Meamaz 45+5 MFD Dual Run Capacitor

Buy the Meamaz 45+5 MFD if your compressor calls for a 45 µF run winding; buy the SOTUBX if it calls for 35 µF. The two are otherwise near-identical CBB65-style round dual-run capacitors: same 5 µF fan section, same 370/440 V rating, same 10,000 AFC fault current, same three labeled terminals. The SOTUBX carries a wider published temperature range (-40 to +85 °C vs -40 to +70 °C) and a stated 30,000-hour life, while the Meamaz lists a ±6% tolerance and a five-year shelf-life replacement warranty. Ratings are thin on both sides, so match the microfarad value on your old capacitor's label first.

• Choose the SOTUBX if your old capacitor is marked 35+5 MFD and you want the wider -40/+85 °C rating and a stated 30,000-hour service life.
• Choose the Meamaz if your old capacitor is marked 45+5 MFD and you want a published ±6% tolerance plus a five-year shelf-life replacement warranty.
