NANO2 885 Series Fuse is designed to protect electric vehicles against severe fault/short-circuit currents, ensuring reliability in harsh environments.

Littelfuse has introduced two series of AEC-Q101-qualified TVS Diode Arrays (SPA Diodes) designed to provide options for very fast acting, high performance over-voltage protection devices. The AQHV and AQHV-C series are designed to provide very fast acting, high performance over-voltage protection devices well suited for power interfaces, passenger charging interfaces, and well as LED lighting modules, and low speed I/Os.

Littelfuse have introduced a series of PLEDs with an ultra-low holding current (just 21mA) that makes the ballast drivers widely used in the output of fluorescent tubes compatible with modern replacement LED strings or tubes. This eliminates the need to scrap otherwise still-working ballasts when replacing fluorescent lighting tubes with LED strings or tubes.

Littelfuse has introduced the smallest cartridge fuse series available that’s rated at 500VAC with current ratings from 40-63A and a 2,000A at 500VAC interrupting rating. The 606 Series high current Cartridge Fuse is designed for overcurrent protection in applications such as high voltage power supply circuits rated up to 23kW. With a 10x32mm cartridge body, a single 606 fuse requires less board space than previous designs that used mu...

  Tired of shuffling through catalogues and datasheets to find the right ESD protection devices, followed by weeks or months of testing, approvals, and prototype building, only to discover you have to start the whole process all over again?

Electric rice cookers are popular appliances that are used for cooking rice. These are pressure cookers that rely on a properly sealed compartment which maintains a high pressure. The pressure built up within the rice cooker compartment can be high enough to blow open the cooker lid if the lid is not properly locked in place when closed. The position sensing lid lock ensures that the lid is securely locked in place.

Littelfuse, Inc. has introduced two series of AEC-Q101-qualified, unidirectional TVS Diode Arrays optimised to protect I/O and power ports against electrostatic discharges (ESDs). SP1053 and SP1054 Series TVS Diode Arrays (SPA Diodes) integrate avalanche breakdown diodes fabricated using proprietary silicon avalanche technology to protect each pin.

Littelfuse, Inc. has introduced a series of AEC-Q101-qualified TVS Diode Arrays optimised to protect automotive Controller Area Network (CAN) lines from damage due to electrostatic discharges (ESDs), electrical fast transients (EFTs), and other overvoltage transients. AQ24CANFD Series TVS Diode Arrays can absorb repetitive ESD strikes above the maximum level specified in industry standards without performance degradation and can safely withs...

Littelfuse has added two 1,200V Silicon Carbide (SiC) n channel, enhancement-mode MOSFETs to their expanding first-generation portfolio of power semiconductor devices. These new SiC MOSFETs are the latest products of a strategic partnership that Littelfuse formed with Monolith in 2015 to develop power semiconductors for industrial and automotive markets. The announcement was made in the Littelfuse booth at the Applied Power Electronics Confe...

  As LED lighting is installed around the world, the need for superior circuit protection to ensure LED luminaires return their promised return on investment has grown. Littelfuse LED lighting surge protection modules are designed specifically to meet the needs of outdoor and commercial LED lighting, with enhanced protection features to guard against catastrophic failure.

  AC power line disturbances are the cause of many equipment failures. The damage can be as elusive as occasional data loss or as dramatic as the destruction of a power supply, LED lightings, industrial system and consumer equipment such as ovens or refrigerators and television sets.

Global fuse company, Littelfuse, has a long history of pioneering innovative products and services to serve the engineering needs of customers and industries. The company has recently introduced the LSP05G. This thermally protected Surge Protective Device is a self-protected device specially designed to be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection. It has been developed with Littelfuse’s ...

  Reed switches and sensors are highly effective solutions for flow sensing applications that can be used for detecting the presence of fluid flow in a system or even measure the rate of fluid flow.

Littelfuse offers designers several protection devices to choose from in an array of form factors and device characteristics that meet the needs of their particular design. As sleeker designs and thinner portable consumer electronics become increasingly popular, Lithium-ion and Lithium- polymer batteries have become the 'go-to' power sources of choice in these applications.
