As power demand in vehicles continues to grow, the need for electrical and fuel economy is driving the necessity for a more efficient automotive electrical system.

Littelfuse is working closely with major automakers and wire harness suppliers to develop and establish new standards of circuit protection for 42 volt automotive electrical systems. Advantages include:

• 42 Volt nominal rating / 58 Volt interrupting rating.
• Unique keying design prevents lower rated fuses from being inserted into the circuit.
• Same performance characteristics as industry standard JCASE™ fuse but modified to work in 42 volt environment.
