INTRODUCTION
This is
thin film, precision, chip resistor. A TCR of 2ppm/C and a tolerance of 0.05% is
standard. TCRs of 1ppm/C, and
5ppm/C and tolerances of 0.025% and 0.1% are also available. This is resistor
uses Ni-Cr thin film deposited onto an
alumina ceramic substrate, resulting in long term stability and a very low TC.
Applications include: Industrial
measurement, control electronics and automatic test equipment.
