Run vs. Start Capacitors: Selection Variables We Work With
Single-phase induction motors need an external phase shift to produce starting torque. Run capacitors stay in circuit continuously to optimize power factor and efficiency, while start capacitors deliver a brief high-torque boost and are disconnected once the motor reaches speed. Our metalized polypropylene film construction is used for run duty because it withstands continuous thermal and electrical stress.
- Capacitance range: Run types typically 2–100 µF; start types from 20 µF up to 1500 µF depending on series.
- Voltage range: Run types 110–450 V AC; start types 110–330 V AC.
- Tolerance: Run types ±5% (J) or ±10% (K); start types ±10% (K) or ±20% (M).
- Operating temperature: CBB60 from -40°C to +85°C; CD60 from -20°C to +65°C.
- Withstand voltage: T-T 2Un/60s and T-C 2Un+1000 V AC/60s (≥2200 V) for CBB60; T-T 2Un+1000 V AC/10s (≥2000 V) for CD60.
- Dissipation factor: ≤0.004 at 1000 Hz for CBB60; ≤0.15 at 100 Hz for CD60.
Materials and Construction
We build capacitors around metalized polypropylene film, slit and wound on high-precision equipment. Depending on the series, the housing may be a metal can with plastic insulation and oil impregnation, or a plastic shell with epoxy resin potting. Vegetable oil impregnation is used in CBB60 types, while CBB65 types use insulation oil impregnation with internal pressure protection.
These construction choices support high insulation resistance, high withstand voltage, low loss and self-healing behavior. The self-healing property helps the capacitor recover from localized breakdowns, which supports stable performance in continuous HVAC duty.
Application Fit Across HVAC, Refrigeration and Appliance Systems
Our capacitors are used in air conditioning compressors, freezer compressors, water pumps, washing machines, range hoods and other single-phase asynchronous motor systems. In three-phase asynchronous motors that use a single-phase power supply, run capacitors also provide the necessary phase shift.
For HVAC and refrigeration projects, the compressor is the most demanding load. A run capacitor with stable capacitance keeps the motor magnetic field even and limits heat buildup and vibration. Start capacitors provide the torque needed to overcome inertia in compressors and pumps that start under load.
Configuration Options and OEM/ODM Support
We supply standard series and configure capacitors to match customer requirements. Options include capacitance value, voltage rating, tolerance class, terminal type, case dimensions and mounting style. Our CBB60 range, for example, covers capacitance from 2 µF to 100 µF with multiple case diameter and height combinations.
For OEM and ODM projects, we review the motor nameplate data, duty cycle and environmental conditions, then propose a capacitor construction that fits the application. We also support private-label packaging and documentation requirements where applicable.
Quality Control and Acceptance Testing
Our production process uses advanced testing equipment with real-time monitoring to support consistent product quality. Automated slitting machines cut metalized film to required sizes, and automated warehousing and logistics systems manage raw materials, semi-finished and finished products.
Capacitors are tested for capacitance, withstand voltage and dissipation factor. Reference standards include GB/T3667.1, GB/T3667.2, IEC/EN60252.0, IEC/EN60252.1, UL810 and VDE0560-8 for applicable series. We can discuss acceptance testing criteria and documentation during project review.

Frequently Asked Questions
What is the difference between a run capacitor and a start capacitor?
A run capacitor stays in the circuit continuously to optimize motor power factor and efficiency. A start capacitor provides a brief high-torque boost during motor starting and is disconnected once the motor reaches operating speed. Run capacitors use metalized polypropylene film for continuous duty; start capacitors use electrolytic construction for intermittent high-capacitance duty.
Which capacitor series should I choose for an air conditioning compressor?
For compressor run duty, CBB65-R1, R2 or R3 are typical choices because they are designed for continuous operation with internal pressure protection. For start assist, CD60 or SPP series provide the high starting torque needed. The final selection depends on motor nameplate data, required capacitance and voltage rating.
Can you produce capacitors to our specifications?
Yes. We support OEM and ODM projects and can configure capacitance, voltage, tolerance, terminal type and case dimensions to match your requirements. Share your motor data and mechanical constraints, and we will propose a suitable construction.
