For power electronics engineers, procurement teams, and high-reliability design projects. High-voltage polypropylene (PP) film capacitors are a cornerstone in modern power supplies, welders, motor drives, EV chargers, and industrial control boards. If you're sourcing reliable box-type capacitors in the 250–2000 VDC class, the Suntan TS09Q series offers electrically stable PP film, low loss characteristics, and wide operating range — all backed by IEC-compliant performance.
TS09Q Product Preview
Below is a visual overview of the Suntan TS09Q series. The image highlights its double-sided metallized polypropylene construction and high-voltage capability, suitable for power supplies, snubber networks, and industrial HV designs.
1. Why PP Film Capacitors Are Preferred in High-Voltage Designs
Polypropylene (PP) film is widely used in high-voltage circuits due to its low dielectric loss, high insulation resistance, and stable temperature behavior, as defined in IEC 60384-1 and IEEE capacitor standards.
These material properties make PP film suitable for EMI suppression, snubber networks, high-frequency PWM stages, resonant converters, and energy discharge applications.
Key electrical advantages of metallized PP film:
• Extremely low dissipation factor (tanδ ≤ 0.001 @ 1 kHz)
• Natural self-healing behavior
• Negative temperature coefficient for capacitance stability
• High insulation resistance for long-term reliability
2. TS09Q Electrical Specifications
Electrical ratings (from official datasheet):
• Reference Standard: GB/T14579 (IEC 60384-17)
• Operating Temperature: −40 °C to +85 °C
• Rated Voltages: 630 VDC, 1600 VDC, 2000 VDC
• Capacitance Range: 0.001 µF to 0.068 µF @ 1 kHz
• Tolerance: ±5 % (J), ±10 % (K)
• Dissipation Factor: tanδ ≤ 0.001 @ 1 kHz
Insulation resistance & dielectric strength:
• C ≤ 0.33 µF → ≥ 50,000 MΩ
• C > 0.33 µF → ≥ 15,000 MΩ·µF
• Voltage Proof: 1.6 × UR for 5 s
• Construction: double-sided metallized polypropylene film
These characteristics match IEC 60384-17 requirements for fixed PP film capacitors and support use in snubber networks, resonant converters, industrial SMPS, and capacitor discharge ignition (CDI) systems.
3. Mechanical Range & Dimensions
Voltage & mechanical portfolio:
TS09Q covers multiple voltage classes from 250 VDC to 2000 VDC, with detailed mechanical variants listed across datasheet pages 1–5.
Typical size window:
• Width (W): 10–32 mm
• Height (H): 9–33 mm
• Thickness (T): 4–18 mm
• Pitch (P): 7.5–27.5 mm
• Lead Diameter (d): 0.6–0.8 mm
This mechanical breadth makes TS09Q suitable for both compact power modules and larger high-voltage topologies.
4. Typical Applications
Where TS09Q is typically used:
• High-voltage SMPS — low loss and high insulation enable stable PWM, LLC resonant, and PFC operation.
• Snubber capacitors for IGBT / MOSFET — PP film supports high dv/dt and fast switching edges.
• Industrial controls & motor drives — −40 °C to +85 °C range fits industrial automation environments.
• Pulse discharge & energy storage — self-healing film supports repetitive high-stress cycles.
• High-voltage AC circuits — includes variants up to 700 VAC (see datasheet page 5).
5. Why Distributors and Procurement Teams Choose TS09Q
Commercial & sourcing advantages:
• Wide voltage and capacitance range: 250 VDC to 2000 VDC, 0.001–0.068 µF.
• Stable supply chain for industrial procurement cycles.
