Surface Mount Thermistors
NSRA Series
Description
The NSRA series surface-mount, end-banded chip thermistors are designed for use on hybrid substrates, integrated
circuits, and printed circuit boards. They have a solder-coated metallization that is suitable for various contact techniques
including wire bond, epoxy, or solder. Since these thermistors are manufactured using the most advanced equipment and
technology available, their dimensional parameters are extremely uniform making them especially suitable for use with
automatic handling and placement equipment. The NSRA series offers a highly reliable structure and exceptional accuracy.
Options include non-standard resistance values and tolerances as well as tape and reel packaging. These thermistors are
used in a variety of industrial applications.
