AEC-Q200 Qualified Surface-Mount Fuses

Littelfuse AEC-Q200 Qualified Surface-Mount Fuses are automotive-grade fuses designed to operate under high working ambient temperatures up to +150°C. These automotive fuses are available in several options (fast-acting, high I²t, and high voltage). Littelfuse 437A, 438A, and 440A fast-acting fuses ensure excellent temperature stability and performance reliability. The 440A fuses feature current ratings from 0.5A to 8A and 63V to 32V maximum voltage rating. The 437A fuses offer 500mA to 4A current ratings and 63V to 32V maximum voltage rating. With a current rating range of 0.25A to 6A, the 438A series has a maximum voltage rating range of 24V to 63V_DC. Littelfuse 885 NANO² series has a 1A to 5A current rating range with a maximum voltage of 450V or 500V.
