Product Precautions
Storage: Shelf life is 12 months. Store at 5~40 and within 10~80% RH. Exceeding this may cause terminal oxidation. Avoid extreme environments (high salt, strong acids/bases, high radiation).
Soldering: Preheat before soldering; temperature difference between preheating and soldering should be within 150. For rework, adhere to specified conditions; excessive heat or repeated rework may cause failure.
Handling: After soldering, avoid applying residual stress to the inductor due to PCB deformation, which can lead to cracking, detachment, or failure. Do not expose to cleaning agents or alcohol, as this can erode the product and cause failure.
Operation: Product temperature rises with current; ensure sufficient margin in design. High static electricity can cause permanent damage; implement static protection. Do not touch any part of the product during energization to prevent electric shock. Consider mutual influence with surrounding components due to magnetic properties.
Application: Suitable for general electronic equipment (AV, communication, home appliances, entertainment, computers, personal devices, office equipment, measurement equipment, industrial robots) under normal operating conditions.
Special Use: For applications requiring high safety and reliability, or where product failure could endanger life, property, or have significant societal impact (e.g., , transportation, aerospace, power control, nuclear, explosive control, traffic control, national defense, disaster relief, safety equipment, emergency medical), consult with the company before use. The company is not liable for consequences arising from use without written consent in such special applications.
