Surface Mount Fuse Datasheet

437A Series

AEC-Q200 Qualiﬁed > 1206 Fast-Acting Ceramic Fuse

RoHS Pb

Description

The 437A Series AECQ-Compliant fuses are specifically tested to

cater to secondary circuit protection needs of compact auto-

electronics applications.

The general design ensures excellent temperature stability and

performance reliability. In addition to this, the high I²t values typical

of the Littelfuse Ceramic Fuse family ensure high inrush current

withstand capability.
