Littelfuse today highlighted the importance of placing circuit protection at the forethought of the electronic engineering community world wide. Bharat Shenoy, Director of Technical Marketing at Littelfuse, delivered this message to thousands of engineers attending the leading industry fair Electronica in Munich, Germany.

Littelfuse has developed the Nano2 485 Series Fuse, a compact (12.1mm x 4.5mm x 4.5mm), surface mountable 600VDC fuse for overcurrent protection of high voltage DC circuits. The 485 Series Fuse is designed for overcurrent protection of high energy DC circuits and applications.

Littelfuse today announced its new series of TVS Diode Arrays (SPA Devices) optimized for protecting telecommunication interfaces such as VDSL and VDSL2 from damage. Each SR70 Series TVS Diode Array is built from four low capacitance, rail-to-rail diodes to provide excellent protection against electrostatic dissipation and lightning-induced surge damage.

Littelfuse announced its new resettable PPTC resistor series, designed for high speed overcurrent protection in applications that require ultra-low internal resistance, ultra-low voltage drop and minimal power dissipation.

Littelfuse has developed a new series of broadband protection Thyristors, designed for use in the tertiary or line driver side protection position for ADSL2 and VDSL2, and the 30MHz bandplan of VDSL2+ applications and general I/O protection functions.

Littelfuse today announced it had introduced TCMOV34S, SMOV34, and SMOV25 Series Varistor products designed to protect high energy circuits. The new TCMOV34S Series Varistor is a 34mm-square-format varistor that combines high maximum surge capability (40kA) with an integrated thermally active element.

Littelfuse has developed a new line of transient voltage suppression diodes for general purpose ESD protection applications. SP1008 Series TVS Diode Arrays are capable of protecting chipsets up to ±15kV with a low dynamic resistance of 1.3 ohms, providing superb clamping performance in a very space efficient footprint.

Littelfuse, Inc. today announces it has introduced itsnew 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 space-constrained electrical systems.

Littelfuse, Inc today announced the addition of the TMOV34S Varistor Series to its Thermally-Protected MOV line of products with UL1449 recognition to the demanding higher range voltage values from 115VAC to 750VAC.

Littelfuse, Inc. today introduced the SP3021 and SP3031 Series TVS Diode Arrays for electrostatic discharge protection of high-speed data lines. The SP3021 and SP3031 Series are ideal for applications that require low capacitance to maintain signal integrity and minimize performance degradation.

Littelfuse, Inc. will celebrate its 85th anniversary this month. The company was founded in 1927 by Edward V. Sundt, who invented the first small, fast-acting protective fuse to prevent sensitive test meters from burning out.

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.
