Differences Between RO4003C and RO4350B

Comparison of Material Composition and Characteristics

When comparing RO4003C and RO4350B, it’s essential to examine their material composition and characteristics. RO4003C is a woven glass reinforced laminate that provides a balanced performance for a wide range of applications, particularly in RF circuits. Its design is optimized for applications that require stable dielectric properties at various frequencies. In contrast, RO4350B features a proprietary thermoset resin system, providing improved thermal stability and lower dielectric loss, making it suitable for high-frequency applications where performance is critical.

Dielectric Constant and Tangent Loss (tanδ) Parameter Comparison

A key differentiator between these two materials lies in their dielectric constants and tangent loss (tanδ) parameters. RO4003C typically has a dielectric constant of around 3.48, with a tangent loss of approximately 0.0027 at 10 GHz. On the other hand, RO4350B offers a lower dielectric constant of about 3.48, but with a significantly lower tangent loss of 0.0015, resulting in better signal integrity and reduced signal degradation over longer distances. This makes RO4350B particularly advantageous for high-speed digital applications and RF designs.

Recommendations for Different Application Scenarios

When considering application scenarios, RO4003C is ideal for standard RF applications, such as antennas and microwave circuits, where cost-effectiveness and stable performance are required. Conversely, RO4350B is recommended for more demanding applications, including telecommunications, satellite communications, and high-frequency circuit designs, where low loss and high reliability are paramount. The Rogers PCB material datasheet provides detailed specifications for both materials, enabling designers to select the most suitable option based on their specific application needs.
