Matters Needing Attention
- When designing the PCB, consider the installation position of non-magnetic shielded components to avoid magnetic interference.
- Do not place this product near magnets or objects with magnetic force.
- Avoid storing the product in environments with high temperature, high humidity, dust, or corrosive substances (salt, acid, alkali, etc.).
- Account for self-heating (temperature rise) during operation in thermal design.
- Use an anti-static wrist strap to prevent static discharge.
- Avoid direct contact with terminals by hands to prevent reduced solderability due to grease.
- Do not excessively bend the terminals to prevent disconnection.
- The product is sensitive to direct impact, which may cause damage to the magnetic core.
- When using potting or gluing, be aware of material shrinkage, potential stress on the core, and compatibility with enameled wire insulation, plastic skeleton, and glue. Potting materials can affect high-frequency characteristics.
- For alloy or non-coated products, surface rust may occur in humid environments but will not affect product characteristics.
- This product is intended for general electronic equipment. For specialized applications (e.g., automotive, medical, military, aerospace, submarine), contact the sales department for consultation.
- Solderability of terminal electrodes may deteriorate if storage time exceeds 12 months.
