These grey film capacitors are precision-engineered for AC motor applications, specifically designed to regulate speed and ensure smooth operation in household fans, ventilation systems, and small appliances. Available in a broad range of capacitance values from 0.047 µF to 4.7 µF, these components offer excellent self-healing properties and long-term stability under continuous electrical load.
With a standard 275V AC rating and compact box-style housing, they are the ideal choice for both manufacturing new cooling units and repairing existing fan motors.
Precision Capacitance Range: Offereing a versatile selection of values including 0.047 µF, 0.22 µF, 0.33 µF, 0.47 µF, 0.56 µF, 0.68 µF, 0.82 µF, 1 µF, 1.8 µF, 2 µF, 3.3 µF, and 4.7 µF to match specific motor torque and speed requirements.
High Voltage Stability: Rated for 275V AC operation, providing reliable performance in standard domestic power environments.
Flame-Retardant Housing: Encased in a durable, grey UL 94V-0 rated plastic box that resists heat and prevents fire hazards during motor malfunctions.
Self-Healing Technology: Utilizes metallized polypropylene film that can recover from internal dielectric breakdowns, significantly extending the component's lifespan.
Low Dissipation Factor: Engineered for high efficiency, minimizing energy loss as heat to keep your fan motor running cool.
Safety Certified: Features multiple international safety marks including UL, VDE, and CQC, ensuring compliance with global electrical standards.
Rated Voltage: 275V AC.
Capacitance Values: 0.047 µF to 4.7 µF.
Color: Grey.
Lead Type: Radial through-hole pins.
Operating Temperature: -40°C to +105°C.
Ceiling & Pedestal Fans: Used as start or run capacitors to control motor speed and rotation.
Exhaust & Ventilation: Reliable timing and motor control for kitchen and bathroom ventilation units.
Small Domestic Appliances: Suitable for air purifiers, humidifiers, and small motorized tools.
Circuit Interference Suppression: Can be used as X2 safety capacitors for EMI filtering in power supply circuits.
Why is my fan spinning slower than it used to? A slow-spinning fan is often caused by a weakened capacitor. Over time, these components lose their ability to hold a charge. Replacing the old unit with a new capacitor of the exact same µF rating usually restores the fan to its original speed.
Can I use a higher µF value to make my fan faster? It is strongly recommended to match the original value. Using a significantly higher µF rating can cause the motor to over-torque and overheat, potentially leading to permanent motor failure.
What does the "X2" or safety mark on the casing mean? The safety markings indicate that the capacitor is designed to fail safely. If it encounters a massive power surge, it will "open" the circuit rather than catching fire, protecting your home and the appliance.
