Measurement Results

EMラボのスプリットシリンダで温度特性を評価した例。誘電率（ε'/Dk）は温度が変化しても比較的変化が少ないことがわかる。
EMラボのスプリットシリンダで温度特性を評価した例。誘電正接（tanδ/Df）が温度によって大きく変化することが確認できる。

Key Point!

  • Dielectric Properties Are Temperature Dependent
  • The degree of change with temperature varies significantly between materials.
  • Evaluating materials under their actual operating conditions is crucial.

The dielectric constant of resins, especially the dielectric loss tangent, varies greatly with temperature, and the degree of change varies from material to material. Therefore, it is essential to evaluate the dielectric constant at the temperature at which the material is actually used. Here, LCP and MPI are compared as an example to easily understand the difference in change with temperature.
