Littelfuse 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.
