›One-Time Fuse

The Littelfuse 40A Glass Tube Fuse (C370942) provides reliable overcurrent protection for 4A circuits with a 40A interrupt rating, operating between -55°C and +125°C. Ideal for automotive, industrial, and telecom applications, it requires proper soldering at 300-350°C and storage in controlled environments. Designers should ensure polarity compliance and thermal management within specified limits, while its ROHS compliance supports modern electronics needs.
