Littelfuse offers NEW MICRO3 Blade Fuses



by Alan Tran

Littelfuse, Inc. (NASDAQ:LFUS), the global leader in circuit protection, today announces it has introduced its new MICRO3™ line of blade fuses. This new line combines two individual fused circuits in a single sub-miniature body, making it an ideal solution for space-constrained electrical systems.

The MICRO3™ is less than 15mm wide and offers the same 5mm terminal spacing and electrical performance as its single-fuse counterpart, the MICRO2™. It is also designed to perform in a wide thermal operating range, from -40°C to over 125°C, and is therefore rated for high temperature (under hood) operation. In addition the MICRO3™ offers a tighter overload tolerance than industry standards (120 sec max @ 135% Ir), which enables customers to further optimize their wiring systems.

The MICRO3™ is available in four different current ratings, ranging from 5A to 15A, with a 32 VDC rating and standard 2.8mm terminals. These products allow for more circuits in a smaller space, helping to decrease harness weight, maximize available area and lessen overall complexity in automotive and other applications.

“The Micro3 allows more fuses to be packaged into a smaller area, thus reducing system costs and helping to solve space constraint issues,” said Julio Urrea, Director of Product Management-Advanced Engineering for the Littelfuse Automotive Business Unit.
