Description
PCF-3 is our cost-optimized dielectric film for RF and microwave applications where budget efficiency matters without sacrificing the core benefits of PTFE-based dielectrics. Its higher ceramic loading (30:70 PTFE-to-ceramic ratio) reduces PTFE resin content — the highest-cost input — while still delivering dependable low-loss performance well beyond standard FR-4.

Why PCF-3
- Highest ceramic content in the series lowers material cost per sheet while retaining PTFE’s core chemical and thermal stability
- Df of 0.0005 still outperforms standard epoxy/FR-4 materials by more than an order of magnitude
- Well-suited for higher-volume RF programs where per-unit cost is a primary design constraint
- Same -200°C to +260°C operating range and chemical resistance as the premium grades
Recommended Applications: Cost-sensitive RF modules, general microwave circuits, industrial sensing, mid-tier automotive radar components
The film's operating temperature range is -200°C to +260°C, and it resists degradation from strong acids, alkalis, and organic solvents. No additional storage or handling precautions are required beyond standard cleanroom practices for PTFE-based composites.
- Operating Temperature Range: The film must be used within -200°C to +260°C to maintain structural and electrical integrity.
- Chemical Compatibility: The film is resistant to strong acids, alkalis, and organic solvents.
How does the 30:70 PTFE-to-ceramic ratio in PCF-3 affect its dielectric loss and cost compared to lower ceramic loading alternatives?
The higher ceramic content (70%) reduces PTFE resin cost while maintaining a dissipation factor of 0.0005, which is an order of magnitude better than standard FR-4. The dielectric constant is 3.5. This trade-off enables cost-effective RF performance for high-volume applications.
What are the thermal and chemical compatibility limits of PCF-3 for integration into harsh environment RF systems?
PCF-3 operates from -200°C to +260°C and is resistant to strong acids, alkalis, and organic solvents, making it suitable for harsh environments such as industrial sensing and automotive radar components.
What handling considerations are required for PCF-3 given its 120 µm thickness and 9 MPa mechanical strength?
The 120 µm thickness and 9 MPa mechanical strength indicate the material is thin and may be brittle. While no specific handling instructions are provided in the source, careful handling to avoid bending or stress is recommended to prevent damage during fabrication.
PCF-3 is a cost-optimized PTFE/ceramic dielectric film with 70% ceramic loading, delivering a dissipation factor of 0.0005 and a wide operating temperature range from -200°C to +260°C, but its low mechanical strength of 9 MPa necessitates careful handling during processing.
Positive
- Cost-optimized high-ceramic loading: 70% ceramic filler reduces PTFE resin content, lowering material cost while maintaining a dissipation factor of 0.0005 and full chemical resistance across -200°C to +260°C.
Trade-offs
- Low mechanical strength (9 MPa): The 9 MPa mechanical strength is substantially lower than standard PCB laminates, requiring careful handling and support during lamination or assembly to avoid cracking or delamination.
