Littelfuse, Inc. has created a “behind-the-scenes” IndyCar weekend Race Experience for the engineering community. The “Speed2Design” promotion, connected to five upcoming races on the 2012 IZOD IndyCar schedule, will bring participants behind the scenes for the weekend to spend time with the team engineers and pit crew behind the Littelfuse co-sponsored No. 11 MOUSER ELECTRONICS/GEICO/KV Racing Technology Chevrolet Dallara driven by IndyC...

Littelfuse Inc. today announced its new EL731 AC/DC Sensitive Earth-Leakage Relay, which can detect ground currents—even in resistance-grounded electrical systems—all the way down to 0 Hz. This makes it ideal for protecting variable-frequency drives (VFDs) that may operate at low speeds, during which AC current approaches DC.

Littelfuse announces the new MICRO3 line of blade fuses. This new line combines two individual fused circuits in a single sub-miniature body, making it an ideal solution for modern space constraints.

Littelfuse announced today that it has won a Supplier Excellence Award from TTI, Inc., a leading electronics distributor. This marks the second consecutive year that Littelfuse has won this award, achieving the bronze level for 2010 performance.

Littelfuse announced the addition of the SP03A Series to its expanding line of TVS Diode Array ( SPA TM family) lightning surge and ESD protection devices. The SP03A is specifically designed for protection of Ethernet and T3/E3 data lines from lightning-induced transients up to a market leading 150A (tP=8/20µs).

Littelfuse introduced its new 804 Series of TE time-lag subminiature fuses, designed to protect AC circuits from damaging overcurrent. The new fuse series is the best in the industry in terms of interrupting capacity and inrush current protection in a TE package, and it is a smaller pitch alternative to 5x20mm glass cartridge fuses.

The Littelfuse POWR-GARD Arc-Flash Relay (PGR-8800) protects electrical systems by detecting arc flash incidents early and economically. Used in general industrial facilities, the PGR-8800 is an easy-to-install, stand-alone product with up to 24 light sensors, including optional fiber-optic cable sensors that can protect difficult-to-reach compartments.

Littelfuse, Inc. today announced the enhanced versions of the SPLV2.8 and SPLV2.8-4 Series which are, respectively, single- and four-channel TVS Diode Arrays (SPATM Family) for ESD (electrostatic discharge) and lightning-induced transient protection.

Littelfuse announced today that it will join Mouser Electronics, a design engineering resource and global distributor for semiconductors and electronic components, in sponsoring Ho-Pin Tung as he enters the qualifying races for the Indianapolis 500 this weekend. If Tung, who has completed a test run topping 220 miles per hour, succeeds in qualifying for the race, he will be the first Chinese national to compete in this event.

Littelfuse announced today that it has won the 2010 Leading Electronic Component Manufacturer Award in the Circuit Protection category, “Leading Circuit Protection Supplier.” This is the second year in a row that Littelfuse won the award, which is sponsored annually in China by the China Electronics Fair, CNTRONICS.com and China Electronic Market Magazine.

Littelfuse introduced its new 977 Series of ceramic body, 5x20mm-size fuses designed for circuit protection in both high-power AC and power-efficient DC applications. The 450VDC rating of the 977 Series sets it apart from other manufacturers’ fuse products.

Littelfuse announced the introduction of the SP1005 and SP1007 Series today. Both series are discrete bidirectional TVS diodes for ESD protection measuring only 0.62x0.32x0.28mm. The SP1005 (30pF @ 0V) offers up to ±30kV ESD protection and 10A (tP=8/20µs) of surge protection with only 0.7Ω of dynamic resistance, providing best-in-class clamping performance. The SP1007 (3.5pF @ 2.5V) can withstand up to ±8kV ESD, which protects up to the m...

Littelfuse has introduced the 215SP Series fuse, a single pigtail fuse that complements Littelfuse’s line of traditional pigtail fuses. Unlike the existing 215 Series, the 215SP Series fuse has one cap at each terminal side, rather than double caps at each side. By doing away with conventional overcapping, Littelfuse was able to offer a ceramic-body fuse with a more compact footprint in the 5x20mm size.

Littelfuse, Inc. has introduced two new series of SIDACtor devices that protect sensitive SLICs (Subscriber Line Interface Circuits) from damaging overvoltage transients caused by lightning and AC power faults. The Pxxx1DF-1 and Pxxx1DF-1E Series Fixed Voltage Protection SIDACtor® devices enhance the reliability of telecom equipment by providing single-port (both tip and ring) protection in a single package.

Littelfuse, Inc. announced the introduction of the SP3011 Series for USB 3.0 ESD protection, a six-channel, ultra-low capacitance diode array packaged in a 3.5x1.35x0.5mm µDFN-14.

Littelfuse, Inc. has introduced its AK15 Series of Transient Voltage Suppressor (TVS) devices to prevent the destruction of expensive electronic gear from high-energy transients. With their 15kA surge current rating, AK15 devices provide the highest level of TVS protection available in the industry. They will be especially useful to manufacturers of mission critical equipment such as cellular telecom infrastructure apparatus, industrial transient...
