Thin Film Chip Type Resistors


Square Thin Metallic Film Chip Resistors


These surface-mounted resistors make the most of their small temperature coefficient.

Features

  • Superior stability, with strong moisture resistance and small changes over time.
  • Superior temperature coefficient (±1ppm/°C).
  • Superior high-frequency properties.
  • Superior current noise properties.
  • Strong resistors against surge.
