Electrical Characteristics

• All test Data is referenced to 25 ambient
• Typical Heat Rating DC Current would cause an approximately T of 40
• Typical Saturation DC Current would cause Lo to drop approximately 30%
• Operation Temperature Range: -55 ~ 125
• The Part temperature (ambient + T) should not exceed 125 under worst case operating conditions.
• Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provisions all effect the part temperature. Part temperature should be verified in the end application.

Announcements (Product Precautions)

• Product shelf life is 12 months under storage conditions: temperature 5~40, humidity within 10~80% RH. Exceeding the shelf life may cause oxidation of product terminals.
• Do not use or store in extreme environments (high salt, strong acid, strong alkali, strong radiation, etc.).
• Preheat before soldering; temperature difference between preheating and soldering temperature is recommended to be within 150.
• When re-disassembling and re-soldering after product soldering, follow the specified conditions. Excessive heating temperature and repeated disassembly may cause product failure.
• After soldering to the PCB, avoid applying residual stress to the inductor due to PCB deformation, which may cause cracking, detachment, or failure.
• Do not expose the product to liquids such as cleaning agents or alcohol, as this may erode the product body and lead to failure.
• Product temperature will rise with increasing current when energized; ensure sufficient margin is considered during design.
• Excessive static electricity can cause permanent damage to the product; pay attention to static protection.
• Do not touch any part of the product during energization to prevent electric shock.
• As a magnetic product, consider potential mutual influence with surrounding components during design.
• This product is suitable for general electronic equipment.
