    Without specific information/schematic, it is impossible to say. Provide a clue as to the application

    It's a simple 555 circuit but I find it difficult finding the right parts on the Internet .

    Poly-film caps are among the best, but usually a bit high priced.

    I just hope the thing doesn't blow up on me. Thank you nonetheless .

    Unlikely to blow up, it will either work or not. the 555 is quite robust, just don't exceed it's voltage rating.
