The PC-58 series is designed for direct insertion into printed circuit boards; fit standard 0.10 inch matrix boards with standard 0.046 inch diameter holes. The PC-58 radial design and provided built in stand-offs reduce board temperatures. Space saving radial terminals reduce the total length requirement compared to axial terminal resistors and increase packaging density possibilities. These compact resistors carry a great overload rating and are coated with a flame resistance vitreous coating.
