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...
