Packard PRMJ108 / TRMJ108 Start Capacitor

The Packard PRMJ108 / TRMJ108 is a high-performance motor start capacitor engineered for intermittent duty on single-phase AC motors. Rated for 108-130 MFD and 330 VAC, this dry electrolytic component provides the necessary torque boost for compressor and motor startup in demanding HVACR applications. Constructed with a moisture and oil-resistant molded plastic case, it is designed to withstand 50/60 Hz operating frequencies with a maximum of 20 starts per hour at three-second durations.

This capacitor features a standard round configuration with a 2-1/16 inch diameter and 4-3/8 inch height, ensuring straightforward fitment in existing motor housings. The dual-type 1/4-inch terminals support both quick-connect and solder connections, facilitating rapid field replacement. Reliable across a wide temperature range of -40°C to 65°C, the PRMJ108 is a critical service part for technicians maintaining water pumps, compressors, and fan motors that require a stable 330V start capacitor.

• Broad Compatibility: Replaces common industry parts including MARS 11063 and JARD 11963.
• Terminal Versatility: Dual blade terminals allow for fast wiring or secure soldering in the field.
• Environmental Protection: The non-polarized resin case prevents oil and moisture ingress, extending component life in unconditioned spaces.
• High Starting Torque: Optimized for motors requiring a powerful boost to overcome initial inertia.

• Can I use this to replace a capacitor with a higher voltage rating? For safety and performance, always match or exceed the original voltage rating. A 330V capacitor can replace a 110V or 250V unit, but cannot be replaced by one rated lower than the circuit demand.
• What causes these capacitors to fail? Frequent cycling (more than 20 starts per hour) or a faulty centrifugal switch that keeps the capacitor in the circuit too long will lead to overheating.
• Does orientation matter during installation? No, these are non-polarized electrolytic capacitors and can be mounted in any orientation within the motor shell.
