Matters Needing Attention
- Consider non-magnetic shielded component placement on PCB to avoid magnetic interference.
- Avoid placing the product near magnets or objects with magnetic force.
- Do not store or use in unsuitable environments (high temperature, high humidity, dusty, corrosive).
- Allow sufficient margin for self-heating during operation.
- Use anti-static wrist straps during handling.
- Avoid direct contact with terminals to prevent reduced solderability due to hand grease.
- Do not excessively bend terminals to prevent disconnection.
- The product is sensitive to direct impact, which can cause damage.
- Be cautious with potting or gluing materials, as shrinkage can induce stress and affect electrical or mechanical properties. Ensure compatibility with enameled wire, plastic skeleton, and glue.
- Surface rust may occur on alloy or non-coated products 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.
