Packard PRMJ161 Start Capacitor

The Packard PRMJ161 Start Capacitor is a professional-grade solution for providing the high-torque surge required to initiate motor rotation in demanding HVACR and industrial pump applications. Rated for 161-193 MFD and 330V, this dry electrolytic capacitor is engineered specifically for intermittent duty in AC motor starting circuits, ensuring reliable performance in high-head-pressure scenarios. Encased in a moisture and oil-resistant molded phenolic resin, the round start capacitor maintains structural integrity across an operating temperature range of -40°C to 65°C.

Designed for universal compatibility, the PRMJ161 features standard 1/4" dual blade terminals for fast, secure wiring. This component is a verified 161-193 microfarad replacement for high-voltage systems requiring a 330V rating, providing a robust 3-second start cycle to reduce strain on motor windings. Whether you are servicing a residential condenser or a commercial air handler, this Packard start capacitor ensures the electrical "kick" needed to get compressors and blower motors up to speed without hesitation.

• Optimized Starting Torque: High 161-193 MFD capacitance range provides the necessary boost for motors under heavy load.
• High-Voltage Resilience: Rated at 330 VAC to handle power surges and high-voltage applications with greater safety margins than lower-rated alternatives.
• Durable Phenolic Housing: Precision-molded case resists common environmental hazards including moisture, oil, and extreme temperatures.
• Universal Compatibility: Standard 2-1/16" diameter and 4-3/8" height design ensures the PRMJ161 fits most standard capacitor brackets and enclosures.
• Reliable Terminations: Secure dual blade terminals facilitate a clean connection for consistent current delivery during the start phase.

• Can I use this 330V capacitor if my old one was 250V? Yes; you can always use a capacitor with a higher voltage rating (330V) than the original, as it provides a higher ceiling for electrical stress. Never use a capacitor with a lower voltage rating than the original.
• Why is my motor humming but not starting? A humming motor often indicates a failed start capacitor that can no longer provide the phase shift required to initiate rotation. Testing the 161-193 MFD output with a multimeter is the standard procedure for diagnosis.
• What does "intermittent duty" mean for this part? This capacitor is designed to be in the circuit only during the first few seconds of motor startup. Once the motor reaches speed, the centrifugal switch or relay should remove the PRMJ161 from the circuit.
