437 Series SMT Fuses

Littelfuse 437 Series SMT Fuses protect circuits against overcurrent in ambient high-temperature situations. These ceramic fuses operate bewteen -55° and +150°C temperatures, providing both high I²t values and inrush current withstand capabilities. The halogen-free 437 series gives users a high performance reliability, with models ranging from 250mA to 8A current rating. These Littelfuse fast-acting, surface mount fuses are suitable for both leaded and lead-free reflow as well as wave soldering. 437 series fuses are ideal for servers, printers, scanners, data modems, LCD displays, and LED lighting applications.
