Littelfuse Introduces 215 Series 15A-25A, 5x20 mm Cartridge Fuses

The latest Littelfuse 215 Series product line extension places the firm at the top of the supply chain for compact, high interrupting capacity, 250VAC fuses.

DES PLAINES, Illinois, December 30, 2008 - Littelfuse, Inc. (NASDAQ/NGS:LFUS) today announced its new 215 Series of 5x20mm ceramic body, time-lag cartridge fuses for high interrupting capacity in a limited space. The new fuses come in 15A, 16A, 20A, and 25A ratings for up to 250VAC service, making Littelfuse the leading supplier of compact, high-current rated cartridge fuses.

The 215 Series time-lag fuses will be of particular interest to designers of power supplies, white goods, air conditioner compressors, and other high-ampere equipment that needs protection under high fault-current conditions. Under fault conditions, the new fuses can interrupt currents as high as 500A at 250VAC, providing a remarkable margin of safety for electronic circuits.

They are used in AC applications, and their small size allows engineers greater flexibility in circuit design. Designers can replace their 6x32mm cartridge fuses with the new smaller footprint 5x20mm size.

All the fuses in this Series are RoHS-compliant/lead-free, and are recognized under UL and CSA component programs. Their opening times are tested in accordance with IEC 60127-2, Standard Sheet 5.


Samples are available immediately. The standard OEM bulk quantity is 1000. For initial orders, lead times are approximately eight weeks ARO; for subsequent orders the lead time is six weeks ARO or less.
