TP Series Material Introduction
TP material is an industry-exclusive high-frequency thermoplastic laminate, formulated with ceramic fillers and polyphenylene oxide (PPO) resin without fiberglass reinforcement. Its dielectric constant (Dk) can be precisely adjusted by modifying the ceramic-to-PPO resin ratio, and it delivers exceptional dielectric performance and high reliability through a specialized manufacturing process. The TP product lineup is classified by copper cladding configuration: TP denotes copper-free smooth surface material, TP-1 refers to single-sided copper-clad material, and TP-2 indicates double-sided copper-clad material.
The dielectric constant of TP series materials is stably tunable within the range of 3 to 25, customized to meet specific circuit requirements. Common Dk values include 3.0, 4.4, 6.0, 6.15, 9.2, 9.6, 9.8, 10.2, 11, 16, and 20, with corresponding part numbers (e.g., TP300, TP440, TP600, TP615). It exhibits low dielectric loss, which increases moderately with frequency but remains negligible within the 10 GHz bandwidth, rendering it ideal for high-frequency applications.
