Installation and Use Precautions

Use within the specified temperature range. Higher temperatures may degrade performance and material quality.
Avoid melting solder on 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. Cutting leads less than 10mm from the resin head can propagate heat to the resin.
When bending leads, maintain a bending radius greater than 1mm. Fixing the component lead wire is recommended during bending or cutting.
Do not apply excessive force to the leads to prevent breakage at the junction.
The ceramic element is fragile; handle with care to avoid excessive pressure or shock, which may cause cracking or chipping.
Evaluate product quality before molding with resin.

Storage Conditions

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

Prohibited Storage/Use Environments

Corrosive or deoxidizing gas (e.g., Chlorine, Hydrogen sulfide, Ammonia, Sulfuric acid gas, Nitric oxide gas).
Volatile or flammable gas.
Dusty conditions.
Vacuum, high pressure, or low pressure.
Wet or humid locations; avoid direct immersion in liquid or washing with liquid.
Places with salt water, oils, chemical liquids, or organic solvents; do not use directly with quick-drying glue.
Strong vibrations.
Other environments with similar hazardous conditions.

Important Note

Ensure your product is equipped with an appropriate fail-safe function to prevent secondary damages from abnormal operation or failure of this product.
