Littelfuse Introduces 804 Series TE UMF Time-Lag Subminiature Fuses
News Release from:
21 July 2011
Littelfuse introduced its new 804 Series of TE time-lag subminiature fuses, designed to protect AC circuits from damaging overcurrent. The new fuse series is the best in the industry in terms of interrupting capacity and inrush current protection in a TE package, and it is a smaller pitch alternative to 5x20mm glass cartridge fuses.
The 804 Series has a compact design that meets the requirements of the IEC 60127-4 standard for universal modular fuse-links (UMF). Unlike pigtail-leaded cartridge fuses, the leads on TE- style fuses need no forming prior to mounting, which simplifies assembly. The fuses have a pitch of only 7.5mm, far less than the space occupied by 5x20mm fuses, giving designers more flexibility in board layout.
Although small in size, the 804 Series fuses have electrical capabilities that allow them to be used as replacements for 5x20mm glass cartridge fuses that are common in many applications. The 804 Series has a high interrupting rating of 150A at 250VAC that ensures the fuses will open safely under high fault currents. In addition, the series provides high inrush-current withstand comparable to 5X20mm glass cartridge fuses.
The new fuse series is available in a broad range of ratings, from 800mA to 6.3A, and carries approvals from UL, PSE, VDE, CQC, and KC agencies. It is fully RoHs compliant.
