Description Littelfuse 437 The Littelfuse 437 series fast melting fuses are specially designed to provide overcurrent protection for circuits operating at high operating temperatures (up to 150 º C). Specially suitable for automotive electronics, LCD displays, data modems, servers, printers, and scanner applications. Working temperature range -55 ° C to+150 ° C, 100% lead-free and RoHS compliant, suitable for lead and lead-free reflow soldering/wave soldering. Surface mounting technology - Ultra miniature fuse holder. Surface mounting fuses are suitable for low voltage applications and can greatly save space (and time). FF type is most suitable for protecting high-value silicon ICs, such as alarm systems, audio/video devices, computer boards, portable phones, power supplies, and medical instruments, etc
