This series of axial leaded resistors is made using the same
foil technology as the S102C. The difference is axial versus
radial leads. Axial leads have the advantage of readily
available auto insertion equipment while the radial leaded
devices may require additional tooling. Also, when
converting from metal film (RNC 55) to foil (VMTA 55) boards
may already be laid out for the axial leaded device. It is worth
noting that for new designs the S102C footprint is the
smallest in the industry (taking into account the need for lead
exit to board pad length allowance).
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.
