Product catalog summary
Overview
Littelfuse offers a wide range of circuit protection solutions for automotive applications, including powertrain, safety, comfort, and infotainment. Their products include fuse boxes, power supplies, lighting, and engine management components.
Product Technologies
Littelfuse provides various circuit protection technologies:
  • Fuses/Footprint Reduction: MICRO2™ and MICRO3™ fuses for space efficiency.
  • Medium Current Cartridge Fuses: MCASE+™ fuses, smaller than JCASE® fuses.
  • Discrete High Current Fuses: High current bolt-down fuses and arrays.
  • ZCase Masterfuse: The smallest high current distribution product.
  • High Voltage Fuses: For electric and hybrid vehicles.
  • Battery Cable Protection: CABLE PRO® protectors for high power cable assemblies.
Environmental Commitment
Littelfuse focuses on eco-friendly product design, eliminating hazardous materials like lead, cadmium, and mercury, and complies with RoHS standards.
Specific Product Details
  • MICRO2™ Blade Fuses: Rated at 32V, designed for high-temperature environments.
  • MICRO3™ Blade Fuses: Feature three terminals and two fuse elements, suitable for high-temperature environments.
  • Low Profile MINI® Blade Fuses: Rated at 58V, designed for space and weight savings.
  • MINI® Blade Fuses: Standard for vehicle circuit protection, rated at 32V.
Usage Limitations
Littelfuse products are not intended for critical applications such as military, aerospace, medical, or life-sustaining devices. Warranties are void if used outside specified applications.
Specifications
Details for various fuses, including MINI®, ATOF®, and MAXI® fuses, are provided. These fuses are designed for automotive and low voltage electronic applications, with specific voltage and current ratings, compliance standards, and temperature ratings.
Time-Current Characteristics
The document includes detailed time-current characteristic curves for each fuse type, indicating the opening time at various percentages of the rated current.
Material and Construction
Terminals are typically made from Ag or Sn plated zinc alloy, and housing material is PA66.
Compliance and Limitations
Littelfuse products are not intended for critical applications unless specified. The use of these products is subject to Littelfuse's Terms and Conditions of Sale.
Ordering Information
Part numbers and package sizes for ordering various fuse types are included.
Applications and Limitations
Littelfuse products are not intended for critical applications where failure could result in injury or property damage. Compliance with Littelfuse's terms and conditions of sale is emphasized.
Conclusion
Littelfuse provides a range of cartridge fuses designed for specific electrical applications, offering features like time delay, inrush current handling, and compact design for space optimization.
Fuse Rating and Temperature Rerating
The document discusses selecting a MINI Fuse rating for an ambient temperature of 105˚C, recommending a 25A or larger MINI Fuse.
Transient Overcurrent Considerations
Transient pulses of inrush current affect the life of automotive fuses. The document includes a melting-current curve comparison between 30A MINI and MAXI Fuses.
I2t and Pulse Cycle Withstand Capability
I2t represents the thermal energy from current flow, crucial for determining pulse cycle withstand capability and selective coordination.
Selective Coordination
In a coordinated system, only the fuse immediately on the line side of an overcurrent opens, keeping upstream fuses closed.
Voltage Drop Across Terminals
The quality of the connection between the fuse and the cable affects performance, with maximum recommended voltage drops provided.
Diffusion Pill Technology
This technology involves mixing molecules to form alloys with lower melting points, enhancing fuse characteristics.
Matching Wire Gauge to Fuse
The document emphasizes matching wire gauge to fuse ratings to protect wiring under overload and short circuit conditions.
Additional Resources
Littelfuse offers online product specifications, printed catalogs, and circuit protection design guides.
