A thermoplastic composition comprises 55 to 97 weight percent of a polycarbonate; 1 to 25 weight percent of a polysiloxane-polycarbonate comprising siloxane units of the formula (I): wherein each occurrence of R is the same or different, and is a C1-30 monovalent organic group, wherein E is 1 to 1,000, and wherein the polysiloxane-polycarbonate comprises 0.1 weight percent to 50 weight percent siloxane units; 1 to 10 weight percent of an impact modifier; and 1 to 10 weight percent of a filler, wherein the filler has a particle size with to D50 less than 2.7 micrometers. The thermoplastic composition has good flame retardance, flexural modulus, impact and surface appearance. A method of making and articles prepared from the thermoplastic composition are also disclosed.
