Technical Specifications

Usage Precautions

• Avoid using water-soluble flux as it may cause corrosion.
• When soldering terminals, avoid applying pressure to the product to prevent displacement, deformation, or degradation of electrical characteristics.
• For double soldering, allow the product to return to room temperature after the first soldering. Continuous heating can cause plastic deformation/aging, terminal loosening/disconnection, and reduced electrical characteristics.
• Prevent flux from infiltrating the product to avoid damage, contact failure, or malfunction.
• Refer to the product diagram for recommended dimensions for printed circuit boards and mounting hole patterns.
• During the overall assembly process, do not apply external force to the product.
• When used under low voltage conditions (below DC1V), poor contact may occur. This product is designed for DC resistance loads and should not be used with other loads (inductive loads, capacitive loads).
• Applying excessive operating force during use or testing may damage the product.
• Store in a cool, dry place at room temperature (25C, within 50% humidity), away from direct sunlight and corrosive gases. Use within 6 months from the date of delivery.

Disposal Information

Products do not belong to hazardous waste. When waste, it can be entrusted to a recycler for recycling and processing.

Transportation Precautions

During transportation, avoid direct contact with water, acidic or alkaline chemicals, or exposure to environments containing such gases. Be mindful of the risk of falling or tipping over. Avoid collisions or squeezing during transit. Maintain moderate temperature and humidity (room temperature 25C, within 50% humidity) to prevent material deformation or oxidation.
