AC START CAPACITOR

High Starting Torque

Through precise capacitance matching (typically 50-500μF), forming a rotating magnetic field and delivering starting torque 2-3 times the rated torque, ensuring reliable motor starting.

Voltage Surge Resistance

Utilizing metallized polypropylene film (MKP) dielectric, the rated voltage is typically 250VAC-450VAC. It can withstand 2-3 times the rated voltage (such as voltage surges during motor starting) and exhibits self-healing properties, ensuring long-term stability.

Capacitance Stability over a Wide Temperature Range

Within an ambient temperature range of -25°C to +70°C, the capacitance variation is <±5%, far superior to electrolytic capacitors, ensuring consistent starting performance in diverse climates.

Long Cycle Life

capable of over 100,000 starting cycles (compared to 10,000-20,000 for aluminum electrolytic capacitors), making it particularly suitable for applications with frequent start-stop cycles (such as compressors and water pumps).

Low Loss and High Energy Efficiency

With a low loss tangent (tanδ) value, energy loss is low, reducing heat buildup during startup and improving overall motor system efficiency.

Compact Structure and High Reliability Design

offering shock and moisture resistance, making them suitable for harsh operating conditions.
