1. A thermoplastic composition comprising:
from about 30 wt % to about 50 wt % of a polymer base resin component;
from about 5 wt % to less than 10 wt % of a polycarbonate component;
from about 2 wt % to about 8 wt % of an impact modifier component;
from about 30 wt % to about 50 wt % of a glass fiber component; and
from about 0.5 wt % to about 8 wt % of a carbon additive comprising carbon fiber,
wherein the composition has a dielectric constant (Dk) of at least 5 at a frequency of from 1 GHz to 30 GHz as tested in accordance with a coaxial method, and
wherein the combined weight percent value of all components does not exceed 100 wt %, and all weight percent values are based on the total weight of the composition.
