Usage Precautions
When designing PCBs, consider the placement of non-magnetic shielded components to prevent magnetic interference. Avoid placing the product near magnets or objects with magnetic force. Do not store in environments with high temperature, high humidity, dust, or corrosive substances (salt, acid, alkali). Allow for thermal expansion due to self-heating during operation. Use anti-static wrist straps to prevent electrostatic discharge. Avoid direct contact with terminals to prevent reduced solderability due to hand grease. Do not excessively bend terminals to prevent breakage. The product is sensitive to direct impact, which can damage the magnetic core. If potting or gluing, be aware of material shrinkage, potential stress on the core, and compatibility with insulation, skeleton, and glue materials, as these can affect electrical characteristics and high-frequency performance. 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), contact the sales department for consultation.
