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.
