Product Overview
The RK73H series of Flat Chip Resistors (Precision Grade) are designed for high reliability in demanding applications. Featuring a small, lightweight form factor and excellent heat and weather resistance due to their metal glaze thick film construction, these resistors offer high stability with a triple-layer electrode structure. They are compatible with automated mounting processes and various soldering methods. These resistors are RoHS compliant with lead-free terminations and AEC-Q200 qualified (except for the 1F type). They are suitable for use in automotive, medical, and aerospace equipment, where failure could lead to significant damage or loss of life, requiring prior consultation with the manufacturer.
