In addition to our catalog products, RCD offers hundreds of design variations as well as a wide range of fully customized components. While some other component manufacturers prefer to produce only their standard product line, RCD has been a “specialty” manufacturer for over three decades. We don’t mind custom and/or difficult items. In fact, we love a challenge, so don’t hesitate to inquire. Single piece quantities to millions of pieces. If you need a resistor that will operate at cryogenic temperatures, in an acidic atmosphere, at frequencies over 100GHz, etc., contact us.
