Leadless
Top/Bottom Terminated Chip Thermistors
U.S. Sensor’s leadless chip thermistor elements are designed for use on
hybrid substrates, integrated circuits or printed circuit boards. They
have silver metallization on their top and bottom which is suitable for
various contact techniques including wire bond, epoxy or solder. Since
they are manufactured using the most advanced equipment and tech-
nology available, their dimensional parameters are extremely uniform,
making the devices especially suitable for use with automatic handling
and placement equipment.
