LTR Series High Power Chip Resistors (Wide Terminal Type) LTR10 / LTR18 / LTR50

Overview

ROHM's wide terminal configuration significantly improves joint strength against mechanical stress caused by board contraction/expansion. In addition, an original resistive element structure and trimming design provides superior anti-surge characteristics and higher rated power.
