What is Rogers RO4003C high frequency PCB?
Rogers RO4003C belongs to the Rogers RO4000 series — a woven-glass reinforced hydrocarbon ceramic laminate engineered to deliver superior high-frequency performance at a competitive fabrication cost. It offers near-PTFE electrical behavior while running on standard epoxy/glass (FR-4) lines.
With a lower dielectric constant of 3.38, RO4003C is the cost-sensitive sibling of RO4350B — ideal for antennas, LNAs, filters and couplers where stable impedance and low loss matter but budget is tight. Andwin keeps genuine RO4003C laminate in stock for fast turnaround.

RO4003C vs FR-4
How It Compares to Ordinary PCB
Rogers 4003C is purpose-built for high frequency; standard FR-4 is not.
| Property | Rogers RO4003C | Standard FR-4 |
|---|---|---|
| Best use | Cost-effective high-frequency RF | Low-loss general digital & power |
| Dielectric constant | 3.38 ± 0.05 (stable) | ~4.2–4.5 (varies) |
| Dissipation factor | 0.0027 @10 GHz | ~0.02 (higher loss) |
| Moisture absorption | 0.06% (lowest) | Higher |
| Cost position | Mid — cheaper than RO4350B | Economy |
| Harsh environment | Aerospace / defense ready | Standard switching boards |
Frequently Asked Questions
1.What is Rogers RO4003C used for?
It is used for high-frequency RF and microwave circuits where cost matters — antennas, LNAs, filters, couplers, automotive radar and base-station front-ends that need low loss and stable impedance.
2. How is RO4003C different from standard FR-4?
RO4003C has a stable dielectric constant (3.38 ± 0.05) and far lower loss (Df 0.0027). FR-4 varies in Dk and loses signal integrity at microwave frequencies, making it unsuitable for precision RF.
3. What is the typical lead time?
Because we keep Rogers RO4003C laminate in stock, typical delivery is 7–10 days for standard builds. Hybrid or high-layer-count jobs are quoted case by case.
4. Can you build hybrid RO4003C + FR-4 stack-ups?
Yes. Hybrid constructions combine RO4003C RF layers with FR-4 for cost-sensitive inner layers while preserving RF performance where it matters.
5. Do you provide samples for evaluation?
Yes, evaluation samples are available. Send your Gerber / BOM or stack-up drawing to sales@andwinpcb.com for a quote.
