Installation and Use Precautions

  • Use within the specified temperature range.
  • Avoid melting solder in the resin head during installation to prevent wire breakage, short circuits, or insulation damage.
  • Do not touch the resin head directly with a soldering iron.
  • When dividing parallel leads, separate them at least 10mm from the resin head.
  • When bending or cutting leads, ensure the bending radius is greater than 1mm and consider fixing the component leads.
  • Do not apply excessive force to the leads to avoid breaking the junction between the lead and the element.
  • Handle with care as the ceramic element is fragile and susceptible to cracking or chipping from excessive pressure or shock.
  • Evaluate product quality before molding with resin.

Storage Conditions

  • Storage Temperature: -10~+40
  • Relative Humidity: 75%RH
  • Environment: Keep away from corrosive atmosphere and sunlight.
  • Period of Storage: 1 year

Prohibited Storage/Usage Environments

  • Corrosive or deoxidizing gas environments (e.g., Chlorine gas, Hydrogen sulfide gas, Ammonia gas, Sulfuric acid gas, Nitric oxide gas).
  • Volatile or flammable gas environments.
  • Dusty conditions.
  • Vacuum, high pressure, or low pressure conditions.
  • Wet or humid locations; avoid direct liquid immersion or cleaning with liquids.
  • Locations with salt water, oils, chemical liquids, or organic solvents; avoid direct use with quick-drying glue.
  • Environments with strong vibrations.
  • Other locations with similar hazardous conditions.
