RIVERSIDE, Calif., June 15, 2010 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of a unique new series of useful design documentation developed to assist designers in selecting the appropriate circuit protection solution for a specific port interface. Bourns® PortNote™ Solutions are a series of one-page documents that provide concise and easily understandable information on relevant compliance standards, Bourns solutions and part numbers, the specific interface schematic and alternative solution references. As the majority of circuit protection products are designed into variations of just a few ports, each Bourns® PortNote™ Solution offers designers a simple starting point for the protection of a particular port.

“Bourns® PortNote™ Solutions are a time-saving design tool that quickly provides an effective circuit protection solution known to work in most typical applications down to the Bourns® part number,” said Dr. Erik Meijer, vice president of circuit protection at Bourns. “PortNote™ Solutions are not intended to replace detailed application notes or the customized solutions provided by our FAE teams, but rather be a useful resource to streamline the circuit protection selection process for a specific port interface.”

Accessible on the Bourns website, Bourns currently has 13 PortNote™ Solutions in its documentation library with more in development and planned for release in the near future. At present, there are four PortNote™ Solutions that cover Ethernet and USB ports for datacom applications; three on HDMI and VHF/UHF coaxial ports for audio/video applications and six show solutions for ISDN, various RJ11 and VDSL ports in telecom designs.  In addition, Bourns offers corresponding Design Kits. Each design kit contains enough Bourns® products to build five of the circuits suggested in the PortNote™ Solution. To view the individual Bourns® PortNote™ Solutions or to inquire about the design kits, go to the Bourns website at http://www.bourns.com/Library.aspx?name=PortNoteSolutions.

Bourns Acquires Central Office Surge Protection Products Assets from Corning Cable Systems LLC

June 22, 2009

RIVERSIDE, Calif., June 19, 2009 — Bourns, Inc. today announces that the company has purchased substantially all of the assets of the central office surge protection products business from Corning Cable Systems LLC, part of Corning Incorporated’s Telecommunications segment. This asset purchase extends Bourns’ current offering of protection products and protection technology and further strengthens Bourns’ position as a leading supplier for central office and remote access cabinet surge protection.  Bourns will consolidate the central office surge protection products operation within its existing design and marketing operation in Riverside, California and manufacturing facilities in Costa Rica and Tijuana, Mexico.

Corning Cable Systems’ central office surge protection products, which include 5-pin, 4-pin, 1-pin protector modules, related protector blocks, connectors and protector panels, are sold principally to Telcos for use in central office and remote access cabinet surge protection applications in the United States, Canada and Mexico.  Selected products are also purchased by manufacturers as components in higher level integrated copper products.  The assets purchased by Bourns do not include any of Corning Cable Systems’ other copper product solutions or European surge protection solutions.

Bourns has previously acquired the communication protection products businesses of Joslyn Electronics and Emerson Network Power as well as Texas Instruments’ solid state primary protection business and the innovative Transient Blocking Unit business of Fultec Semiconductor.

“Bourns is committed to supplying the best and most reliable electronic solutions to satisfy the diverse needs of our customers,” said Dr. Erik Meijer, vice president of circuit protection for Bourns.  “With Bourns’ more than 30 years experience in this market, the company is uniquely positioned with our internal production of components such as gas discharge tubes, thyristors, PTC thermistors and the newly-acquired transient blocking units, which together form the very heart of modern telecom protection.”

Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that the company has developed freeXpansion™, a new technology added to the company’s entire line of Multifuse® surface mount polymer positive temperature coefficient (PTC) resettable fuses.  This new technology increases the performance of the fuse with the ability to handle higher currents and voltages, improves its resistance stability and allows for a smaller footprint.  Due to its new freeXpansion™ technology, Bourns is able to introduce one of the smallest families of PTCs on the market with a size of 0603, designated the Bourns® MF-FSMF Series.  Bourns’ Multifuse surface mount devices manufactured using the freeXpansion™ process is designed to meet next-generation electronics smaller size and high current requirements.  Bourns® Multifuse® devices are an optimal overcurrent circuit protection solution for broad range of equipment including products with USB 2.0, USB 3.0 and HDMI ports and in consumer electronics and automotive electronics applications.

Polymer PTC resettable fuses expand when an overcurrent event occurs and contracts when they reset.  The freeXpansion™ technology allows the device to freely expand and contract without mechanical restrictions for more stable performance, extended product life and to be manufactured in a smaller size.

“Bourns® Multifuse® products with freeXpansion™ offer distinct competitive advantages for our customers enabling reliable circuit protection across a broader range of applications,” said Brian Ahearne, technical marketing manager for Bourns’® Multifuse® products.  “As more and more electronic products become portable with design space constraints, Bourns® Multifuse® devices match application requirements for a smaller package and the ability to handle higher currents and voltages helping our OEM customers protect their valuable circuits from overcurrent conditions.”

Bourns® Multifuse® devices act as critical circuit protection components by limiting dangerous current surges, such as short circuits in electrical equipment.  These devices provide secure protection as they react to an overcurrent event by changing from a very low resistive state to a very high resistive state.  This is also referred to as the positive temperature coefficient effect or PTC effect.  Once the overcurrent surge has passed, the Multifuse® device automatically resets to its low resistive state and allows the equipment to resume operation.
