Resistive Element: Metal glaze thick film (ruthenium oxide based) screen-printed on alumina ceramic substrate and fired at high temperature.\n\n2. Triple-Layer Electrode: Silver-palladium inner electrode, nickel barrier plating, and tin outer plating for reliable solder joint formation.\n\n3. Power Rating: 0.33W at 70\u00b0C ambient, derating linearly to zero at 155\u00b0C.\n\n4. Precision: The E96 845 Ohm value with \u00b11% tolerance provides precise resistance for voltage divider and feedback applications.","pin_description":"\n
