RIVERSIDE, Calif., June 29, 2009 — Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of two new power resistor products that provide high power density in a small form factor designed to satisfy the growing demand for low-power, space-saving devices. Designated Bourns® models CRF1206 and CRM2512-FT, the new power resistors are also RoHS compliant. Bourns’ CRF1206 power resistor is constructed from a stamped metal alloy boasting an extremely low one watt of power in an ultra small 1206 size package. Bourns’ CRM2512-FT is a new surface mount power resistor that features a power rating of two watts in a small 2512 size package.

The small package size and low power features of Bourns’ CRF1206 make it an ideal solution for power supplies and stepper motor drive applications. Bourns’ CRF1206 features low inductance (less than 5 nH) and resistance values of 0.01 and 0.02 ohms with TCRs of +100 PPM/°C and +75 PPM/°C respectively. This new power resistor is also rated to handle overload conditions equivalent to five times the operating power for up to five seconds.
Bourns’ CRM2512-FT power resistor meets ITU-T K.20, K.21 and K.45 basic test requirements within rated limits for telecom ports designed for Metallic Ended Line Test (MELT) functionality such as ADSL and VDSL2 hardware or for telecom line test equipment.
“Bourns’ latest extension of the company’s fixed resistors product line provides a viable solution for engineers facing the increasing challenge of designing highly integrated circuitry with low power consumption in ever smaller form factors,” said Cathal Sheehan, product marketing manager for Bourns Resistive Products Division. “The company is committed to continuing the tradition of introducing the latest generation of power resistor products to help solve design challenges for designers and our OEM customers worldwide.”

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® Model 3046 Linear Motion Potentiometer Used in the Mini Power Tool in the Hubble Telescope Repair Mission

Recently, a variety of repair functions were completed on the Hubble Telescope by NASA astronauts. Bourns is proud to have been part of this successful mission. Our Model 3046 linear motion potentiometer is used as a trigger in the Mini Power Tool. NASA mechanical engineers designed a mechanism around the potentiometer to actuate it. The housing protected the potentiometer and made a very smooth and solid-feeling trigger for control of the tool.

If any of you were watching, the second time they used the tool, it did not work. Apparently, the astronauts forgot to charge the battery. With a fresh battery, the Mini Power Tool preformed flawlessly.
