Model 0449001.MR
Description Littelfuse 449 The Littelfuse 449 series NANO2 surface mounted fuses have enhanced surge withstand characteristics, which help solve the annoying open circuit problem caused by accommodating surge currents, which often cause fast melting fuses to open. The 449 series NANO2 surface mounted fuse is suitable for a wide range of applications. Delay small size low-temperature derating # # # Recognized by CSA, UL # # # Surface mounting technology _ Ultra miniature fuse holder # # Surface mounting technology Surface mounted 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
