407 Time-Lag Fuses

Littelfuse 407 Time-Lag Fuses are explicitly designed to provide overcurrent protection to circuits that operate under high working ambient temperatures up to +150°C and high inrush currents. The fuses feature a general design that ensures excellent temperature stability and performance reliability. The high I2t time-lag fuses avoid nuisance openings due to a high inrush and surge current inherent in the system. Littelfuse 407 Time-Lag Fuses offer high current ratings in a small 1206 size package.
