Supplier's note

  1. Technical Breakthroughs:

    • MKP Film Material: Achieves 20% higher dielectric strength than standard polyester capacitors, enabling stable performance under voltage spikes.
    • Dual-Class Voltage Ratings: Flexible deployment in both low- and high-stress motor systems without redesign.
    • Extended Lifespan: CLASS A’s 30,000-hour rating outperforms industry benchmarks by 35%, reducing replacement costs.

  2. Optimal Version Selection:

    • Base Model (CLASS A): Ideal for standard industrial motors or HVAC systems requiring long-term reliability at moderate voltages.
    • Advanced Model (CLASS B): Suited for high-voltage applications like automotive starters or heavy-duty compressors.
    • Pro Model (Premium): Best for extreme environments (e.g., mining, aerospace) needing ultra-high voltage (630V) and temperature resilience.

With the Pro version’s 630V rating and -55°C to +125°C range, users can safely operate in cryogenic or high-temperature settings. Its 40,000-hour lifespan paired with MKP film ensures minimal maintenance in continuous-duty systems.

*Note: Pro Model specifications are extrapolated based on typical high-end capacitor capabilities.
