Self-Healing Metallized Film – Metallized polypropylene film dielectric provides self-healing properties. When a breakdown occurs, the metallized film vaporizes around the fault, isolating it and allowing continued operation, extending capacitor service life and improving system reliability.
Flame-Retardant Square Plastic Case – Square plastic case with flame-retardant material and epoxy filling provides excellent moisture resistance, insulation, and safety. Compact size fits tight spaces in fan motors and small appliances.
Stable Capacitance Over Time & Temperature – High capacitance stability across operating temperature range (-40°C to +85°C), ensuring consistent motor performance in both cold-weather and high-heat applications.
Low Dissipation Factor – Dissipation factor ≤2×10⁻⁴ at 100Hz. Low internal power losses reduce heat generation and improve energy efficiency of AC motors.
Wide Capacitance & Voltage Range – Available from 0.5μF to 20μF and 250VAC to 500VAC, covering fan motors, ventilation fans, air conditioner fan motors, and small single-phase pumps.
Compact & Lightweight – Square plastic case is smaller and lighter than cylindrical or aluminum case capacitors, ideal for space-constrained fan motor and appliance designs.
Stable Bulk Supply – Standard models ship in 15–25 days, supporting rolling replenishment and reducing inventory capital occupation.
OEM & ODM Support – Custom logo, capacitance value, voltage rating, terminal type, and packaging available. Can produce according to customer specifications.
Batch Traceability – Strictly quality inspection with every shipment; SGS/BV third-party inspection supported.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
