Df around 0.002, Dk about 3.5 and wideband stability — why TC350 serves communications, radar, medical and automotive designs, and where it beats RO4003C and FR-4.
Low Dielectric Loss: TC350 has an extremely low dielectric loss (Df), typically around 0.002. This characteristic allows for effective reduction of signal loss during high-frequency signal transmission, ensuring the integrity and stability of signals.
High Dielectric Constant: The dielectric constant (Dk) of this material is approximately 3.5, making it suitable for applications that require a higher dielectric constant. A high dielectric constant allows for more compact circuit designs, particularly advantageous for modern miniaturized electronic devices.
Wideband Performance: TC350 performs excellently across a wide frequency range, meeting the demands for high-speed data transmission. Its good frequency characteristics make it an ideal choice for modern communication and data processing.
Excellent Thermal Stability: TC350 exhibits high thermal stability with a thermal weight loss temperature typically reaching 300°C. This means that the material can operate reliably in high-temperature environments, making it suitable for high-power applications such as power amplifiers and RF modules.
Low Coefficient of Thermal Expansion: This material has a relatively low coefficient of thermal expansion, which helps maintain stable electrical performance during temperature fluctuations, reducing signal distortion caused by temperature changes. This is especially important in high-frequency circuit designs.
Outstanding Mechanical Strength: TC350 demonstrates excellent tensile and compressive strength, capable of withstanding significant mechanical stress in complex circuit designs, ensuring the integrity and stability of circuits.
Good Machinability: This material supports laser cutting and precision machining, facilitating complex circuit layouts and meeting the needs of modern high-density circuit designs.
Good Chemical Stability: TC350 exhibits good resistance to various chemicals, maintaining stable performance in harsh chemical environments, making it suitable for industrial applications.
Moisture Resistance: The material performs well in high-humidity environments, effectively preventing moisture ingress and ensuring that electrical performance remains unaffected.
Comparison with RO4003C: Compared to RO4003C from the RO4000 series, TC350 shows clear advantages in electrical performance, especially in dielectric loss and thermal stability. TC350’s higher dielectric constant makes it suitable for more compact circuit designs.
Comparison with FR-4: Although FR-4 materials are more competitively priced, TC350 excels in high-frequency and high-power applications, meeting stricter performance requirements. Furthermore, TC350’s thermal stability and mechanical strength make it more reliable in harsh environments.
