VTA52 through 56, VMTA55, VMTB60 Vishay Foil Resistors Bulk Metal® Foil Technology Tubular Axial-Lead Resistors, Meets or Exceed MIL-R-39005 Requirements FEATURES • Temperature Coefficient of Resistance (TCR): • • • • • • • • • Any value and tolerance available within resistance range 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.
