Thin Film Dual Chip Resistors

Thin Film Dual Chip Resistors

Product Features

        • Two Resistors on a single chip area.
        • Available styles are common or isolated node.
        • The nature of this design lends itself to tightly matched TCR and electrical tolerance, with resistance rations within 0.01% (value dependent).
        • Can be used in Non-Magnetic Applications
