LITTELFUSE
Circuit protection and power semiconductors
About the manufacturer
Founded in the United States in 1927, Littelfuse manufactures circuit-protection and power-control solutions. The company has expanded its portfolio from fuses into surge protection, power semiconductors and devices for automotive and industrial systems. Combining established fuse technologies with modern power electronics allows Littelfuse products to be used across a broad range of equipment architectures.
Fuses, varistors, TVS diodes and surge devices provide different protective functions and are not interchangeable. The company also develops power semiconductors and switching components used in power electronics.
Protection selection covers voltage, continuous current, trip current, interrupt rating, surge energy and coordination with other elements. Protection must be evaluated in the complete circuit, not from a single headline parameter.
Applications
Areas where LITTELFUSE products are used include:
- power supplies
- automotive systems
- industrial power electronics
- battery systems
- data-line protection
- network devices
