The µF (microfarad) or MFD rating indicates the capacitor’s capacitance value. It determines how much electrical energy the capacitor can store and release. Always match the recommended value mentioned on your motor or appliance.

No. Using a higher µF capacitor than specified can damage the motor, cause overheating, or reduce equipment life. Always use the exact recommended capacitance range.

Using a lower value may cause weak starting torque, slow motor speed, humming noise, or failure to start properly.

• Start Capacitor: Provides extra torque during motor startup.
• Run Capacitor: Helps maintain smooth and efficient running during operation.

Yes, if the capacitance and voltage ratings match. However, oil-filled capacitors usually provide better heat dissipation and longer life in heavy-duty applications.
