Matters Needing Attention:
- Consider non-magnetic shielded component placement to avoid magnetic interference.
- Keep away from magnets or objects with magnetic force.
- Avoid storage in high temperature, high humidity, dusty, or corrosive environments.
- Allow for thermal design margin due to self-heating during operation.
- Use anti-static wrist straps during handling.
- Avoid direct contact with terminals to prevent solderability issues 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.
- When potting or gluing, consider potential stress on the core and skeleton, and check for material compatibility to avoid performance degradation or damage.
- 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 (e.g., automotive, medical, military, aerospace, submarine), contact the sales department for consultation.
- Storage within 12 months under conditions of -10 to 40C and 70% RH is recommended to maintain terminal electrode solderability.
