Environmental Considerations

  • This product is for general electronic use. RALEC is not responsible for damages, costs, or losses resulting from the use of this product in special environments. Confirmation with RALEC is required for other applications.
  • Customers intending to use this product in special environments (e.g., high temperature/humidity, corrosive atmospheres like sea breeze, Cl2, H2S, NH3, SO2, NO2, unverified liquids, unverified resins/coatings) must have product characteristics and reliability approved separately.
  • Cleaning after soldering is recommended, even when using no-clean flux, especially if using water-soluble cleaning agents.

Transient Overload Precautions

  • This product may lose functionality due to transient overload. Ensure manufacturing processes and storage prevent transient currents exceeding product specifications.

Handling and Operation Precautions

  • Protect resistor edges and protective coating from mechanical stress during operation.
  • Handle printed circuit boards (PCBs) with care when separating or fixing them to support structures, as PCB bending can cause mechanical stress on the resistors.
  • Use resistors within their rated power range. Exceeding the rated power can lead to temperature rise and potential equipment damage.
  • If the resistor is expected to receive significant pulsed load impacts, set up the operating environment accordingly before use.
  • Evaluate and confirm product use in your specific application, implementing fail-safe designs to ensure system safety.

Storage and Handling Conditions

  • Storage: 255, 6015% RH for two years.
  • Avoid adverse environments such as sea breeze, corrosive gases (Cl2, H2S, NH3, SO2, NO2), direct sunlight, and condensation.
  • Ensure correct box orientation during transport and storage. Avoid dropping or crushing boxes to prevent damage to electrodes or the body.
