Rogers RO4003C is a high frequency circuit board material that has some notable features and application areas. Here are some key information about Rogers RO4003C:

Electrical Properties: 

RO4003C has a dielectric constant Dk of 3.38 +/-0.05 and a dielectric loss Df of 0.0027 (at 10 GHz), which indicates that it has low dielectric constant tolerance and low loss, making it suitable for high-frequency applications.

Material Composition: 

This is a proprietary glass cloth reinforced, ceramic filled hydrocarbon composite material that combines the electrical properties of PTFE/glass cloth with the processability of epoxy/glass cloth.


The RO4003C is available in two different glass cloth configurations, 1080 and 1674, all with the same electrical performance specifications.

Process Control: 

This material has undergone strict process control and has a Z-axis thermal expansion coefficient of 46ppm/℃, similar to copper, ensuring excellent dimensional stability.

Thermal Properties: 

The glass transition temperature (Tg) of RO4000 series materials is greater than 280°C (536°F), ensuring dimensional stability within the circuit processing range.



RO4003C is fully compatible with traditional PCB manufacturing technology and does not require special pre-treatment, such as plasma treatment required for PTFE sheets.

Flame Retardant rating: 

RO4003C material is not brominated and therefore cannot meet the UL 94V-0 flame retardant rating standard. For applications requiring this level of flame retardancy, consider RO4835™ and RO4350B™ high frequency boards.

Typical Applications: 

RO4003C is suitable for a variety of high-performance applications, including microstrip lines, cellular base station antennas, automotive radars and sensors, point-to-point microwave communications, power amplifiers and RFID antennas.

Stock Thickness: 

The thickness of RO4003C high frequency boards regularly stocked by Borui Circuit Company is 8mil, 12mil, 16mil, 20mil, 32mil and 60mil.


RO4003C is manufactured using a similar process to FR-4 but at a lower cost, giving it an advantage in performance-sensitive, high-volume applications.

Product Specifications: 

Rogers RO4003C sheet has a detailed specification parameter list. These parameters are very important for engineers when designing and selecting materials.

Processing Guidelines: 

Rogers Corporation provides processing guidelines for RO4003C sheet, which are critical to ensuring proper handling and optimal performance of the material during manufacturing.

Company Culture: 

Rogers Corporation emphasizes its corporate culture, dedicated to driving, protecting and connecting the world, which reflects the company's mission and values.


Product Series: 

Rogers Company provides a variety of high-frequency circuit boards, RO4003C is one of them. Understanding the entire product range can help users select the right materials for specific application needs.

Production Experience: 

Some professional PCB manufacturers, such as Shenzhen Xinchenger Electronics Co., Ltd., have many years of experience in producing high frequency PCB circuit boards and focus on using materials such as Rogers 4003C.

Application Fields: 

In addition to the applications already mentioned, RO4003C sheets may also be used in other high-performance electronic devices, especially in environments that require high frequency and low loss.

Data Sheet: 

Rogers Corporation provides a data sheet for RO4000 series high frequency circuit boards, which may contain detailed technical specifications and performance data of RO4003C.

Market Supply: 

There are multiple suppliers on the market providing RO4003C sheets, which provides users with the opportunity to choose different suppliers and compare prices and services.

Environmental Considerations: 

Since RO4003C material is not brominated, it may not meet certain environmental standards, which may affect some applications or markets that have strict environmental requirements.
