Category
The C1669507 is a 1.5kA ceramic tube fuse designed for robust overcurrent protection in low-voltage AC/DC circuits. With a 2.5A current rating and 300V DC / 250V AC voltage limits, it features a disposable design for easy replacement. Suitable for automotive, industrial, and renewable energy applications, it operates reliably between -55°C and +125°C. Key considerations include soldering at high temperatures, avoiding static discharge, and ensuring proper thermal management in high-power layouts. Market strengths lie in its temperature tolerance and compliance certifications, while limitations include higher cost and lack of reset functionality.
