Packaged in the 0603 (1608 metric) footprint, it delivers 0.1W power rating with a TCR of \u00b1100 ppm\/\u00b0C. The anti-sulfuration design uses high sulfuration-proof inner electrode material, making it highly reliable in environments with sulfur-containing atmospheres such as automotive and industrial settings.","working_principle":"The RK73H resistor uses a metal-glaze thick film element on a ceramic substrate with laser trimming for precision resistance values. The anti-sulfuration construction features a special inner top electrode material resistant to silver migration and sulfur corrosion. Nickel barrier terminations provide anti-leaching protection during soldering. The device maintains stable resistance under harsh environmental conditions including high temperature, humidity, and sulfur exposure.","pin_description":"
