The part number **288MDCL450KTN** refers to a high-performance **Aluminum Electrolytic Capacitor**, specifically a "Motor Start" or "Motor Run" type typically designed by manufacturers like *United Chemi-Con (UCC)* or similar industrial component brands. Below is a detailed breakdown of the technical specifications and characteristics of this component. --- ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 28.8 µF (Nominal) | The amount of charge the capacitor can store. | | **Voltage Rating** | 450 VAC | Maximum Alternating Current voltage it can handle. | | **Tolerance** | ±10% (K) | The "K" in the part number signifies a 10% tolerance range. | | **Series** | MDCL | Industrial grade, often used in motor applications. | | **Termination** | T / N | Refers to terminal type (often quick-connect lugs). | --- ### 2. Breakdown of the Part Number The alphanumeric string follows a standard manufacturer coding logic: * **288**: Represents the capacitance value (28.8 Microfarads). * **MDCL**: The series designation (High-voltage AC application series). * **450**: The Rated Voltage (450 Volts AC). * **K**: Tolerance code (K = ±10%). * **TN**: Packaging or Terminal configuration code. --- ### 3. Key Applications This specific capacitor is built for heavy-duty electrical environments. Common use cases include: * **Motor Start/Run:** Providing the necessary phase shift to start or maintain the rotation of single-phase induction motors. * **HVAC Systems:** Used in air conditioning compressors and fan motors. * **Industrial Pumps:** Ensuring stable torque in water or chemical pumps. * **Power Factor Correction:** Improving the electrical efficiency of small-scale industrial machinery. --- ### 4. Safety and Installation Because this is a high-voltage AC capacitor, several safety factors must be considered: 1. **Discharge:** Capacitors can hold a lethal charge even after power is disconnected. Always discharge before handling. 2. **Mounting:** Ensure the casing is properly secured to withstand the vibrations of a motor. 3. **Polarity:** As an AC capacitor (Motor Run/Start), it is generally **non-polarized**, meaning it can be connected in either direction within an AC circuit.
