Built for High Voltage & High dv/dt

The TS09S series offers rated voltages up to 3000VDC and transient surge tolerance of up to 1.5×UNDC, with dv/dt values reaching 3361 V/μs. This makes it ideal for demanding applications like:

• IGBT protection
• Switched-mode power supplies (SMPS)
• AC filtering for power circuits

Stable Internal Design for Harsh Environments

Each capacitor features:

• Extended double metallized electrodes (polyester + polypropylene)
• Internal series connection to enhance insulation strength
• UL 94 V-0 flame-retardant plastic case with thermosetting resin
• Tinned brass lug for direct IGBT mounting

This robust construction ensures reliable thermal performance, low self-inductance, and long-term durability.

Low ESR & High Current Capability

At 100kHz, TS09S capacitors deliver ESR as low as 2.5mΩ and support peak currents of over 3000A, depending on the capacitance. This enables:

• Efficient energy delivery
• Reduced thermal stress
• Enhanced protection for sensitive components

Optimized for AC Filtering

With capacitance values ranging from 0.047μF to 9μF and a climatic category of 40/85/56, the TS09S is perfect for AC applications in:

• Industrial motor drives
• Control panels
• Renewable energy inverters
• High-voltage AC/DC converters

Engineered for Longevity & Safety

Conforming to IEC 61071, TS09S capacitors offer:

• High insulation resistance (≥15,000 MΩ or IR×C ≥ 5,000s)
• Surge and overvoltage durability
• Minimal self-inductance (<1nH/mm lead spacing)

These features result in long service life and cost-effective integration into critical systems.

Conclusion

If you're designing for high-performance AC filtering, fast switching circuits, or need robust pulse endurance, Suntan TS09S delivers the reliability and stability needed to meet the challenge.
