Packard PMJ88 Start Capacitor

The Packard PMJ88 Start Capacitor is a high-duty cycle component engineered for fractional horsepower motors and compressors requiring a torque boost during startup. Rated at 88-108 MFD (microfarads) at 125VAC, this round electrolytic capacitor is built to EIA-463-B standards, ensuring reliable performance in demanding HVACR applications. Its compact 1-7/16-inch diameter and 2-3/4-inch height allow for seamless integration into standard motor housings and control boxes. Designed for intermittent duty, the PMJ88 effectively handles 20 starts per hour, providing the capacitive reactance needed to shift phase windings and overcome initial inertia. Technicians often source this as a direct 88-108 MFD 110V/125V replacement for faulty OEM start capacitors in domestic refrigeration and light commercial air conditioning units. The rugged plastic casing protects internal foil and electrolyte from environmental stressors, while dual quick-connect terminals simplify field installations and electrical diagnostics.

• Durable Construction: Moisture and oil-resistant plastic case ensures longevity in high-humidity mechanical rooms.
• Universal Compatibility: Replaces common industry part numbers including Mars 11005 and JARD 11905.

Common Questions

What causes an 88-108 MFD capacitor to fail prematurely?
Frequent short-cycling or a stuck potential relay can leave the start capacitor in the circuit too long, leading to internal pressure buildup or "venting." Always check your relay during replacement.

Can I use a capacitor with a higher voltage rating than 125V?
Yes, you can substitute a higher voltage rating (e.g., 250V) as long as the MFD range stays 88-108, but you should never use a lower voltage rating than the original specification.

Is this capacitor suitable for continuous run motor applications?
No, this is an electrolytic start capacitor designed for intermittent duty only. For phase-shifting during continuous motor operation, a run capacitor must be used.
