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.
