• Voltage Rating: 150V AC — The capacitor is rated for 150V AC, meaning it is suitable for alternating current (AC) applications with voltages up to 150V.
• Type: Run Capacitor — A run capacitor is used in applications where continuous operation is required, such as in AC motors, HVAC systems, and pumps. It helps to improve the motor’s efficiency and performance by providing a phase shift to the motor windings.
• Lot Size: Lot of 3 Capacitors — The lot includes 3 individual capacitors, making it a bulk offering for applications that require multiple units or for spares in case of failure.

Features:

1. Run Capacitor Design: This capacitor is designed to operate continuously in motors and other electrical equipment. It helps maintain the motor’s efficiency by continuously providing power factor correction and reducing energy loss during operation.
2. Capacitance Value: 133µF capacitance is suitable for medium to high-power motors, particularly for applications such as air conditioning units, pumps, fans, or compressors.
3. Voltage Rating: 150V AC means this capacitor is rated for use with alternating current (AC) circuits, and it can handle voltages up to 150V without risk of failure.
4. Durability: Run capacitors are typically designed for long-term reliability, with many capable of operating in harsh conditions like high temperatures and constant electrical stress.
5. Bulk Purchase: A lot of 3 capacitors makes it suitable for businesses or DIY projects that require multiple units, whether for repairs, replacements, or ongoing system maintenance.

Common Applications:

• AC Motors: This capacitor is commonly used in motors for air conditioners, refrigeration units, fans, and pumps. It helps improve the efficiency of the motor by stabilizing the electrical supply.
• HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, run capacitors like the DCM133T150DG18 are essential for ensuring the compressor and fan motors operate efficiently.
• Pumps & Compressors: Run capacitors are used in various pumping systems and compressors to ensure continuous, efficient operation.
• Electrical Equipment: General use in electrical equipment that requires continuous operation and efficient motor performance.

Characteristics:

1. Polarized: Run capacitors like the DCM133T150DG18 are typically non-polarized, meaning they can be connected in either direction, unlike electrolytic capacitors which must be installed with the correct polarity.
2. Long-Term Operation: Run capacitors are designed for continuous use and are different from start capacitors, which are used temporarily during motor startup. Run capacitors are built for sustained performance.
3. Stable Performance: These capacitors maintain a stable capacitance value even during long-term operation, providing consistent performance and improving motor efficiency.
4. Compact Form Factor: This capacitor is designed to fit into smaller spaces, making it useful for systems where space is limited but efficiency is crucial.

Installation Tips:

1. Mounting: Ensure proper mounting in your system to prevent vibration, which could lead to damage. Run capacitors are often mounted within motor casings or HVAC systems.
2. Voltage Check: Always ensure that the operating voltage of your system does not exceed the rated voltage of the capacitor (150V AC). Overvoltage could result in capacitor failure.
3. Check for Overheating: While run capacitors are designed to handle continuous operation, excessive heat can reduce their lifespan. Ensure proper ventilation around the capacitor and maintain temperature within the recommended limits.
4. Avoid Short Circuits: When installing, make sure there are no short circuits or contact with other conductive surfaces that could cause capacitor damage.
