The C1665055 disposable fuse provides robust overcurrent protection for 250V AC/300V DC systems within -55°C to +125°C operating ranges. Its 1.5kA interrupt rating and 1A current rating make it suitable for industrial control, automotive, and renewable energy applications. Designers should prioritize proper thermal management and adhere to soldering guidelines to ensure reliability. While cost-effective for volume production, limited stock availability and lack of polarized variants may require alternative solutions in specific scenarios.
