High-Dk Ceramic-Filled PTFE Laminate
FJY1000B-M
A 10.2-class dielectric platform for compact RF components and antennas
FJY1000B-M is a high-dielectric-constant, ceramic-filled PTFE laminate with woven-glass reinforcement for miniaturized RF and microwave circuits. It is positioned for designs currently based on Rogers AD1000 or Taconic RF-10 where compact geometry, low loss and dimensional stability are key selection requirements.
Key Performance
Designed around the electrical and mechanical variables that determine RF yield
FJY1000B-M supports repeatable high-frequency performance from PCB fabrication through field operation.
High-Dk Miniaturization
The 10.2 dielectric platform reduces the physical wavelength in the substrate, enabling smaller resonators, antennas and passive RF components.
Low-Loss High-Frequency Operation
Controlled dissipation helps preserve efficiency and selectivity in compact filters, couplers and antenna feed structures.
Dimensional and Handling Stability
Woven-glass reinforcement improves rigidity, fabrication handling and layer-to-layer consistency in compact circuit geometries.
Thermal and PTH Reliability
Low expansion and useful thermal conductivity support plated-through-hole durability and stable operation under temperature cycling.

Use these typical values for preliminary comparison and request the current product data sheet before final stack-up release.
| Property | Typical value / positioning | Design relevance |
|---|---|---|
| Dielectric constant (Dk) | 10.2 class at 10 GHz | Impedance geometry, phase velocity and circuit size |
| Dissipation factor (Df) | 0.0026 | Dielectric attenuation and RF power efficiency |
| Moisture absorption | 0.03% | Electrical stability in humid operating environments |
| Thermal conductivity | 0.73 W/m·K | Heat transfer through the dielectric |
| CTE, X / Y / Z | 9 / 12 / 26 ppm/°C | Registration, thermal cycling and PTH reliability |
| Material construction | Ceramic-filled PTFE + woven glass | Electrical stability, handling and fabrication behavior |
Values are typical design references, not guaranteed specification limits. Final material substitution requires review of the current data sheet, copper configuration, thickness tolerance, PCB process and application-level validation.
Typical Applications
Application areas aligned with the material’s dielectric and thermal profile
GPS and GNSS patch antennas
Microstrip patch and ceramic-style antennas
Compact filters, resonators and couplers
Power dividers and passive RF components
Aircraft collision-avoidance systems
Satellite communication components
Material Selection
When to specify FJY1000B-M
Choose FJY1000B-M when reducing RF circuit size is a primary design objective and the material must still provide low loss, stable impedance and reliable PCB processing.
Selection reference
Evaluate the complete construction—not Dk alone—when qualifying a second source or migrating an established RF design.
