Caution for Use

1. Environmental Conditions:Avoid exposure to corrosive gases (e.g., Cl2, H2S, NH3, SOx, NOx), volatile or flammable gases, dust, vacuum, high humidity, salt water, oil, chemical liquids, and solvents.Do not use in vibratile places or environments with excessive pressure.
2. Application Limitations:Do not use in applications requiring high reliability, such as aircraft, aerospace, undersea, medical, transportation, and disaster prevention equipment.
3. Fail-Safe Function:Ensure appropriate fail-safe functions are implemented to prevent secondary damage caused by abnormal operation or failure of the device.

Handling and Storage

1. Voltage and Current:Do not apply abnormal voltage or current exceeding the specified maximum values.
2. Temperature:Use within the specified temperature range to avoid deterioration of characteristics or material.
3. Mounting:Avoid excessive tensile stress (9.8N) between the resin case and lead.Do not apply excessive force (9.8N) to the lead to prevent breakage or cracking.
4. Water and Solvent:Do not immerse the product in water or any solvent for cleaning.
5. Coating:Evaluate the quality of the product before coating to avoid stress-induced failures.
6. Soldering:Use rosin type or non-activated flux (chlorine content < 0.2%).Do not dip the body into flux; coat only the lead wire.Pre-heat without melting the soldering material.Soldering temperature: 360°C max.Soldering time: 4 seconds max per terminal.Number of soldering: 1.
7. Storage:Store in a sealed container with a drying agent.Temperature: -10°C to +40°C.Humidity: < 75% RH (not dewing condition).Use within 6 months after shipment.

Mounting Instructions
