24 Apr 2019
Littelfuse, Inc., incorporated on November 25, 1991, is a supplier of circuit protection products for the electronics, automotive and industrial markets. The Company operates through three segments: Electronics, Automotive and Industrial. In addition to the portfolio of circuit protection products and solutions, the Company offers electronic reed switches and sensors, automotive sensors for comfort and safety systems and a range of electromechanical and electronic switch and control devices for commercial and specialty vehicles, as well as protection relays and power distribution centers for the control and distribution of electricity.
The Electronics segment provides circuit protection components for overcurrent and overvoltage protection, as well as sensor components and modules to manufacturers of a range of electronic products. The segment covers a range of end markets, including consumer electronics, telecommunications equipment, medical devices, lighting products and white goods. The Electronics segment's offerings include fuses and protectors, positive temperature coefficient (PTC) resettable fuses, varistors, polymer electrostatic discharge (ESD) suppressors, discrete transient voltage suppression (TVS) diodes, TVS diode arrays protection and switching thyristors, gas discharge tubes, power switching components, fuseholders, reed switch and sensor assemblies, insulated gate bipolar transistors (IGBT) blocks, and related accessories.
The Company's fuses are used in a range of electronic products, including mobile phones, flat-screen televisions (TVs), computers and telecommunications equipment. The Company markets these products under PICO II and NANO2 SMF brand names. The Company's product line offers both radial leaded and surface mount products. Varistors are ceramic-based devices that provide transient overvoltage and surge suppression for automotive, telecommunication, consumer electronics and industrial applications. The Company's product line offers both radial leaded and multilayer surface mount products. The company's PULSE-GUARD line of ESD suppressors are used in personal computer (PC) and PC peripherals, digital consumer electronics and wireless applications. Discrete diodes, diode arrays and protection thyristors are fast switching silicon semiconductor structures. Discrete diodes protect a range of applications from overvoltage transients, such as ESD, inductive load switching or lightning, while diode arrays are used primarily as ESD suppressors. Protection thyristors are commonly used to protect telecommunications circuits from overvoltage transients, such as those resulting from lightning. Applications include telephones, modems, data transmission lines and alarm systems. The Company markets these products under TECCOR, SIDACtor, Battrax and SPA brand names.
Gas discharge tubes are primarily used in telecommunication interface and conversion equipment applications as protection from overvoltage transients, such as lightning. Power switching components, such as switching thyristors and IGBTs, are used to regulate energy to various types of loads commonly found in industrial and home applications. These components are activated from control circuits or interfaced to computers for more complex load control. Typical applications include heating, cooling, battery chargers and lighting. Magnetic sensing products are used to monitor, sense and measure magnetic fields in a range of applications. The Company's product offerings include a line of reed switches, reed based sensors and hall effect sensors. Reed switches are non-contact magnetically operated devices that provide an output based on the electrical load during the presence of magnetic field. They are used in a range of applications, including security, medical, fluid monitoring, telephones, fitness equipment, metering, toys, white goods, and consumer and industrial controls. Reed switch sensors utilize reed switch technology in various packaging configurations with custom enclosures, terminations and connectors to provide an application specific product as a final assembly. Key applications include fluid level monitoring, position sensing, fluid flow and proximity sensing. Hall effect sensors utilize hall chip technology to sense magnetic fields to provide ratio metric output based on magnetic fields. Key applications include motor speed sensing, directional sensing, rotation, and linear sensing. The Company also supplies fuse holders, fuse blocks (including OMNI-BLOK), and fuse clips to customers that purchase circuit protection devices from the Company.
The Automotive segment provides circuit protection and sensor products to the worldwide automotive original equipment manufacturers (OEM) and parts distributors of passenger automobiles, trucks, buses and off-road equipment. In addition, the Company supplies duty power distribution modules, switches and relays to the commercial vehicle industry. The Company also sells its fuses, including blade fuses and high current fuses, battery cable protectors, and varistors, in the automotive replacement parts market. The Company also supplies wiring harness manufacturers and auto parts suppliers worldwide. The Company's automotive fuse products are marketed under ATO, MINI, MIDI, MEGA, Masterfuse, JCASE and CABLE PRO brand names. Products sold into the market include speed, position, and direction sensors, occupant safety sensors, solar sensors, fluid level, and quality sensors, fuel heating systems, rotary sensors for comfort applications, and water in fuel sensors. Its products also include power distribution modules, low current switches, high current switches, solenoids and relays, electronic switches, battery management products, ignition key switches and trailer connectors.
The Industrial Segment provides circuit protection products for industrial and commercial customers. Its products include power fuses and other circuit protection devices, including protection and time delay relays, which are used in commercial and industrial buildings and equipment, such as heating, ventilation and air conditioning (HVAC) systems, elevators, and machine tools. The Company also supplies industrial ground fault protection in mining and other industrial operations.
The Company manufactures and sells a range of low-voltage and medium-voltage circuit protection products to electrical distributors and their customers in the construction, OEM and industrial maintenance, repair and operating supplies (MRO) markets. The Company also designs and manufactures portable custom electrical equipment for the mining and utility industry in Canada, as well as protection relays for the global mining, oil and gas, and general industrial markets. Power fuses are used to protect circuits in various types of industrial equipment and in industrial and commercial buildings. Major applications for power fuses include protection from overload and short-circuit currents in solar, motor branch circuits, heating and cooling systems, control systems, lighting circuits, solar and electrical distribution networks. The Company's POWR-GARD product line features the Indicator series power fuse used in both the OEM and MRO markets. The Indicator technology provides visual blown-fuse indication at a glance, reducing maintenance and downtime on production equipment. The Indicator product offering is used in motor protection and industrial control panel applications.
Protection relays are used to protect personnel and equipment in mining, oil and gas, and industrial environments from excessive currents, over voltages, and electrical shock hazards called ground faults. Major applications for protection relays include protection of motor, transformer, and power-line distribution circuits. Ground-fault relays are used to protect personnel and equipment in wet environments, such as underground mining or water treatment applications where there is a greater risk for electricity to come in contact with water and create a shock hazard. Littelfuse custom-engineered electrical equipment is designed and built for use in harsh or demanding environments.
The Company competes with Eaton Corporation, Bel Fuse Inc., Bourns Inc., EPCOS, On Semiconductor Corporation, STMicroelectronics NV, Semtech Corporation, Vishay Intertechnology Inc, Amphenol Corporation, Pacific Engineering, MTA, CTS Corporation, Sensata Technologies Holding NV, TE Connectivity Ltd, GE Multilin and Mersen.
