TS09Q 630V–2000V Film Capacitor Guide for Distributors
A technical education guide for sourcing teams, component brokers and global distributors who need a reliable polypropylene film capacitor line for high-voltage applications.
Scope:
This note focuses on TS09Q metallized polypropylene film capacitors in the 630V, 1000V and 2000V range, from a distributor and cross-reference perspective.
Detailed electrical curves and derating data should be taken from the official datasheet.
1. What Makes TS09Q Attractive to Distributors?
Unlike electrolytics, polypropylene film capacitors behave predictably under high voltage stress and temperature swings.
For distributors, this means fewer returns, fewer cross-reference issues, and a smoother supply chain with repeatable performance across batches.
- SMPS high-voltage DC filtering
- Lighting ballasts and LED drivers
- General HV buffering
- Inductive load control
The TS09Q uses a metallized polypropylene structure with controlled self-healing, improving long-term reliability in demanding power designs.
2. Voltage Range, Construction and Expected Lifetime
The TS09Q is available in 630V, 1000V and 2000V versions. Polypropylene film capacitors in this range typically provide:
- Low dielectric loss for high-voltage filtering stages
- Stable capacitance over a wide temperature window
- Self-healing capability that localizes faults and preserves service life
- Predictable ESR for SMPS power stages and snubber positions
These characteristics make cross-reference work easier for distributors – part selection is more about case size and lead spacing, less about unexpected drift or failure modes.
3. Mechanical Outline and Product Appearance
From a stocking perspective, TS09Q keeps a standardized box-film outline with straight leads, making it a practical fit for:
- General-purpose HV filter positions on through-hole PCBs
- Retrofit of legacy box-film capacitors with similar pitch
- Compact SMPS boards that still rely on THT components
4. Inside the Manufacturing Process (Video)
This type of video is often used by distributors’ FAE teams to justify long service life claims and to build confidence in alternative or second-source proposals.
5. When to Recommend TS09Q to Your Customers
TS09Q can be positioned as a stable, high-voltage capable substitute when design engineers or buyers request:
- Long service lifetime in SMPS or ballast designs
- Heat-resistant PP structure instead of electrolytics in hot zones
- Low-loss filtering at 630–2000V with predictable behaviour
- Stable supply with competitive MOQ and clear series roadmap
For BOM tools, TS09Q can be tagged as:
“HV polypropylene film capacitor – 630V/1000V/2000V – box type, general-purpose filtering”.
