Usage Precautions
- Consider non-magnetic shielded component placement to avoid magnetic interference.
- Do not place near magnets or magnetic objects.
- Avoid storage in high temperature, high humidity, dusty, or corrosive environments.
- Account for self-heating during operation in thermal design.
- Use anti-static wrist straps.
- Avoid direct contact with terminals to prevent decreased solderability due to hand grease.
- Do not excessively bend terminals.
- The product is sensitive to direct impact, which can damage the magnetic core.
- When potting or gluing, be aware of material shrinkage, potential stress on components, and compatibility with insulation layers, skeletons, and adhesives. Potting materials can affect high-frequency characteristics.
- For alloy or non-coated products, surface rust may occur in humid environments but does not affect characteristics.
- This product is intended for general electronic equipment. For specialized applications (automotive, medical, military, aerospace, submarine, etc.), contact the sales department for consultation.
- Solderability of terminal electrodes may deteriorate if storage time exceeds 12 months.
