End Banded Chip Thermistor
RB Series 0603 End-Banded Chip Thermistors
Description
Littelfuse surface mount end-banded thermistor elements are
designed for use on hybrid substrates, integrated circuits or printed
circuit boards. They have a solder coated metallization which is
suitable for various contact techniques including wire bond, epoxy
or solder. Since they are manufactured using the most advanced
equipment and technology available, their dimensional parameters
are extremely uniform making the devices especially suitable for
use with automatic handling and placement equipment.
