1. An electrical connector that comprises at least two opposing walls between which a passageway is defined for receiving a contact pin, wherein the walls have a width of about 500 micrometers or less, the walls being formed from a polymer composition that comprises a polymer matrix containing at least one liquid crystalline polymer having a glass transition temperature of about 30° C. or more in an amount of about 30 wt. % or more of the composition, wherein the polymer composition exhibits a dielectric constant of about 4 or less and a dissipation factor of about 0.02 or less, as determined at a frequency of 10 GHz, wherein the liquid crystalline polymer has a total amount of repeating units derived from naphthenic hydroxycarboxylic and/or naphthenic dicarboxylic acids of about 10 mol. % or more, repeating units derived from 4-hydroxybenzoic acid in an amount from about 1 mol. % to about 20 mol. %, and repeating units derived from aromatic dicarboxylic acids in an amount from 25 mol. % to about 30 mol. %, and wherein the polymer composition comprises a fibrous filler containing glass and having a dielectric constant of about 5.5 or less at a frequency of 1 GHz.
