Susumu's Thin-Film Precision Resistor Series

Susumu’s new URG series of thin-film chip resistors offers an improvement in reliability as well as in the linearity of its Temperature Coefficient of Resistance (TCR) compared to the high standard set by the existing RG series.

The URG series offers better absolute tolerance of resistance, at ±0.01%, than any other thin-film chip resistor on the market. It also offers the lowest TCR of ±2ppm/°C. It offers all the advantages of the thin-fi lm type of resistor, such as low noise of -25dB to -35dB, and support for high frequencies up to 1GHz. In addition, the linearity of the URG series’ TCR makes it easy to develop an appropriate compensation algorithm.

For applications that require extreme precision and reliability, Susumu now offers a wide choice of resistor families, providing in addition to the URG series:

  • The RG-PV series offering tolerance of ±0.02% and TCR of ±5ppm/°C
  • The RG-LL series with tolerance of ±0.01% and TCR of ±2ppm/°C
  • ±0.02% maximum drift for load life (2,000 hours at 70°C)
  • ±0.05% humidity bias drift
  • ±0.02% temperature cycle drift
  • ±0.02% high-temperature exposure drift
  • Stable when exposed to atmospheric sulfur
  • EIA standard package sizes: 0603, 0805 and 1206
  • Precision industrial instruments
  • Test and measurement instruments
  • Automotive electronics
  • Laboratory-grade scales
