Littelfuse  announced that Gordon Hunter, Chairman, President, and Chief Executive Officer, will transition to the role of Executive Chairman, effective Jan. 1, 2017. Dave Heinzmann, Chief Operating Officer, will assume the position of President and Chief Executive Officer at that time and will join the company’s board of directors, bringing the size of the board to eight members.

Littelfuse will showcase cutting-edge circuit protection technology designed for the full LED lighting system from the power input all the way to the LEDs themselves, at the Strategies in Light trade show. Littelfuse representatives will be available to discuss new technologies, trends, and components in Booth 630 at the show, held at The Sands Expo & Convention Center in Las Vegas, Nevada, from February 24–26, 2015.

Protection superior to circuit breakers for outdoor LED lighting and telecommunication base transceiver station applications Littelfuse, Inc., the global leader in circuit protection, has introduced two series of compact, high surge withstand fuses, both capable of withstanding up to 20 lightning-induced high current surges without performance degradation. The 328 and 688 Series Fuses offer protection superior to that of circuit breakers, providing short-circuit and overload protection and ensuring long-term reliability for outdoor applications that operate at high surge exposure ...

Protection superior to circuit breakers for outdoor LED lighting and telecommunication base transceiver station applications

By Teddy To, Product Manager and Phillip Havens, Segment Manager • Littelfuse, Inc. As LEDs find their way into more outdoor applications they are at higher risk for ESD and other electrical transients. HB LEDs (those with sapphire or SiC substrates and in the future AlN and GaN substrates) are especially susceptible, and when the first LED in a string fails, the whole string goes dark. Few engineers know all the considerations of specifying circuit protection for LED strings. For example, a recent category of devices, called open LED protecto...

Littelfuse, Inc. (NASDAQ/NGS:LFUS) has introduced the PLED5HT Series circuit protection device that increases LED lighting string reliability. This new device, available in an SOT-89 package, maintains LED string brightness while improving LED reliability for the growing market for outdoor LED lighting and high-intensity LED applications with current draw up to 700 mA.

Littelfuse, Inc. has introduced the PLED5 circuit protection device that provide unique 3-in-1 protection for LED strings, including open LED protection, ESD and lightning protection, and protection against reverse battery/power connections. The new device is particularly useful for maintaining brightness and reliability in the growing market for outdoor LED lighting and high-intensity LED applications.

Recently, Littelfuse Inc. has introduced the PLED 6 series, an open LED protector that provides a switching electronic shunt path when a single LED in an LED array fails as an open circuit. This ensures that the entire array of LEDs will continue to function even if a single LED in the array does not.
