Company Overview
Founded in 1927 and headquartered in Chicago, Illinois, USA, Lite Electronics is a leading global provider of circuit protection solutions. For more than 95 years, Littelfuse Electronics has been powering a sustainable, connected, and safer world. Global business covers more than 20 countries. Products are available in a variety of industrial, transportation, and electronics end markets, almost everywhere, at all times.
Main products:
Circuit Protection Products:
Fuses: Littelfuse provides various types of fuses, including fast fuses, slow fuses and high breaking capacity fuses. These fuses are widely used in automotive, industrial equipment, consumer electronics, and communications to effectively protect circuits from overcurrent and short-circuit faults.
Transient Voltage Suppression Diode (TVS): A TVS diode is a semiconductor device used to protect circuits from transient voltage shocks. With fast response time and high energy absorption capacity, the TVS diodes of Littelfuse can effectively suppress the transient voltages generated by lightning strikes, electrostatic discharges and switching transients, and protect sensitive electronic components.
Varistor: A varistor is a voltage-dependent resistor whose resistance decreases rapidly as the voltage increases. The varistor can be used for overvoltage protection, when there is an overvoltage in the circuit, the varistor will quickly turn on, dissipate the overvoltage energy, and protect other components in the circuit.
