Thin Film Chip Resistors

Yageo AT Series

Sulfur resistant thin film high precision chip resistor -
AT Series

Yageo's automotive grade sulfur resistant, thin film, high precision, high stability chip resistor offers case sizes from 0402 to 1206, resistance range of 10 Ω-1 MΩ, narrow tolerance of ±0.1%, ±0.25%, ±0.5%, ±1% and low TCR of ±25, ±50 ppm/°C, with power rating of 1/16 W-1/4 W. The robust AT series design is an excellent solution for automotive electronics applications where high temperature/moisture resistance and superior anti-sulfuration characteristics are required.


  • AEC-Q200 qualified, Production Part Approval Process (PPAP) available
  • Superior resistance against sulfur-containing environments (according to ASTM B809-95)
  • Lithography process (exposure and development) for inner electrode and resistive layer, high reliability
  • High precision and stability
  • Low TCR, low electrical noise


  • Temperature Cycling: ±0.1%
  • Anti-FOS: ±4% (105°C, 750 hours)
  • Life/Endurance: ±0.1% (70°C), ±0.3% (125°C)
  • Biased Humidity (85°C/85% RH): ±0.1%
