Table of Contents
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??F to 0.068??F @ 1?kHz
? Tolerance: ±5?% (J), ±10?% (K)
? Dissipation Factor: tanδ ? 0.001 @ 1?kHz
Insulation resistance & dielectric strength:
? C ? 0.33??F → ? 50,000?MΩ
? C > 0.33??F → ? 15,000?MΩ·?F
? 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
