Known in the industry as **rogers ro3003**, this material delivers ultra-stable dielectric performance, low loss, and excellent mechanical consistency, making it a preferred choice for demanding RF designs. When evaluating **[ro3003 substrate](https://www.bestpcbs.com/blog/2026/04/ro3003-pcb-material/)**, engineers typically focus on three critical aspects: dielectric stability, signal loss, and manufacturability. RO3003 addresses all three, which explains its widespread use in automotive radar, 5G infrastructure, and high-frequency communication systems. ![RO3003™ PCB Material](https://www.bestpcbs.com/blog/wp-content/uploads/2026/04/9fea449a1ec14984a91fccd2beb6e9fc.png) **RO3003™ PCB Material** ## What Is RO3003 Material? **[RO3003 material](https://www.bestpcbs.com/blog/2025/12/ro3003-pcb-material-thickness-datasheet-cost/)** is a **ceramic-filled PTFE composite laminate**, part of the RO3000 series. It is engineered to provide consistent electrical properties across frequency and temperature ranges, which is essential for RF circuit performance. In practical engineering discussions, this material may also be referred to as: - ro3003 rogers - rogers ro3003 pcb - rogers duroid ro3003 However, it is important to clarify that while “duroid” is sometimes used generically, **rogers duroid ro3003** is not part of the RT/duroid family but belongs to the RO3000 series. Key material characteristics of Rogers RO3003: - Non-woven ceramic-filled structure - No glass fiber weave (reduces signal distortion) - Extremely stable dielectric constant - Low moisture absorption - Compatible with high-frequency PCB fabrication ## RO3003 Datasheet Overview **Category** **Property** **Typical Value** **Notes** **Material Type** Base Material Ceramic-filled PTFE Stable ro3003 substrate for RF **Electrical Properties** RO3003 dielectric constant 3.00 ± 0.04 @ 10 GHz Also called rogers ro3003 dielectric constant Design Dk ~3.16 Used for simulation RO3003 loss tangent 0.0010 @ 10 GHz Low loss RF performance Volume Resistivity 10⁷ MΩ·cm High insulation Surface Resistivity 10⁷ MΩ Reliable signal isolation Dielectric Breakdown >31 kV/mm Strong electrical strength **Thermal Properties** Thermal Conductivity 0.50 W/m·K Helps heat dissipation Tg (Glass Transition Temp) N/A (PTFE-based) No traditional Tg Thermal Coefficient of Dk -3 ppm/°C Excellent stability Decomposition Temperature (Td) >500°C High thermal endurance **Mechanical Properties** Density 2.1 g/cm³ Higher than FR4 Tensile Strength ~200 MPa Good mechanical strength Flexural Strength ~150 MPa Supports rigidity **CTE (Thermal Expansion)** X-axis 17 ppm/°C Stable dimension Y-axis 16 ppm/°C Balanced expansion Z-axis 25 ppm/°C Good via reliability **Moisture & Safety** Water Absorption 0.04% Low moisture uptake Flammability UL94 V-0 Meets safety standard **Processing** Lead-Free Process Compatible Suitable for RoHS RO3003 prepreg Not standard Use bonding film instead **Thickness Options** RO3003 thickness 5–60 mil (0.127–1.524 mm) Also called rogers ro3003 thickness **Copper Foil** Copper Weight 0.5 oz – 2 oz typical Custom available **Cost Factors** RO3003 price Higher than FR4 Depends on thickness & volume ## RO3003 Dielectric Constant The **[ro3003 dielectric constant](https://www.bestpcbs.com/blog/2025/12/ro3003-pcb-material-thickness-datasheet-cost/)** is tightly controlled at **3.00**, making it ideal for controlled impedance design. Engineers often select **rogers ro3003 dielectric constant** when: - impedance matching must remain stable across temperature - phase consistency is required in RF networks - signal integrity must be maintained at GHz frequencies ## RO3003 Loss Tangent The **ro3003 loss tangent** (0.0010) is considered very low, which helps reduce: - insertion loss - signal attenuation - heat generation in RF traces This makes **ro3003 pcb** suitable for high-frequency circuits where even small losses can affect system performance. ## RO3003 Thickness Options The available **ro3003 thickness** and **rogers ro3003 thickness** typically include: - 5 mil (0.127 mm) - 10 mil (0.254 mm) - 20 mil (0.508 mm) - 30 mil (0.762 mm) - 60 mil (1.524 mm) Choosing the right thickness depends on: - impedance requirements - mechanical rigidity - multilayer stack-up design For RF engineers, thickness directly impacts trace width and impedance control. ## Is RO3003 Available as Prepreg? A common question in RF stack-up design is about **ro3003 prepreg** availability. RO3003 is primarily supplied as a **laminate**, not a traditional prepreg like FR4 systems. However: - bonding films or compatible PTFE-based prepregs can be used - hybrid stack-ups (RO3003 + FR4) are possible with proper process control For multilayer RF PCB builds, selecting the correct bonding material is critical to avoid delamination and maintain electrical consistency. ## What is RO3003 used for? RO3003 is used in high-frequency applications such as RF antennas, automotive radar, 5G base stations, and microwave circuits. Because of its low loss and stable dielectric properties, ro3003 pcb is ideal for systems operating in GHz ranges. It is commonly found in: - automotive radar (24 GHz / 77 GHz) - ADAS systems - 5G base stations - RF antennas - Microwave filters and couplers - Satellite communication systems In these applications, the stability of the **ro3003 substrate** directly affects overall system reliability. ## How Much Does RO3003 Cost? The **ro3003 price** or **rogers ro3003 price** depends on several factors: 1. Thicker laminates (e.g., 30 mil, 60 mil) typically cost more due to higher raw material usage and processing complexity. 2. Rolled copper (RA) used for high-frequency applications is more expensive than standard electrodeposited copper, but it delivers better signal performance. 3. Prototype quantities usually carry higher unit costs, while volume production significantly reduces the **rogers ro3003 price**. 4. Multilayer RF boards, hybrid stack-ups, and tight impedance control requirements increase fabrication cost. 5. RF materials like **rogers ro3003** are subject to global demand fluctuations, which can influence pricing and lead time. ## RO3003 PCB Manufacturing Services at EBest At **[EBest Circuit (Best Technology)](https://www.bestpcbs.com/)**, we provide end-to-end support for **rogers ro3003 pcb** projects, from early design validation to full-scale production.
