RIVERSIDE, Calif., January 28, 2014 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of new high Power TVS diode models in SMD packaging for use in AC and DC power line applications. The new models feature high current bidirectional port protection meeting IEC 61000-4-5 8/20 µs current surge requirements and are RoHS* compliant. Designated Bourns® Models PTVS15-058C-SH and PTVS15-076C-SH, these Power TVS diodes offer enhanced performance stability and increased reliability. Designed using advanced silicon technology Bourns’ new devices deliver lower clamping voltage under surge compared to Metal Oxide Varistor (MOV) technology. The SMD package provides a 20% reduction in peak clamping voltage compared to an equivalent through-hole device because of its lower lead inductance. The result is reduced electrical stress on the protected circuitry. Additionally, the SMD package simplifies assembly and can reduce costs by eliminating the extra design requirements in cases where the Power TVS diode is the only through-hole component on the printed circuit board.

“Bourns’ Power TVS diodes are becoming increasingly popular because they provide robust circuit protection against power line surges and indirect lightning strikes in AC and DC power supplies used in telecom and other exposed applications,” said Ben Huang, Semiconductor Product Line Manager at Bourns, Inc. “We designed these new models with specific packaging technology giving our customers the benefit of a highly reliable solution that meets the growing protection demands of today’s high power applications.”

Bourns’ new Power TVS diode models also exhibit an excellent surge response versus temperature, with a maximum surge current rating at 150 °C, which is 70% of their rated value at 25 °C. Both models provide very high surge current protection with a peak pulse current rating of 15 kA. The Bourns® Model PTVS15-058C-SH features a 58 V standoff voltage and the Bourns® model PTVS15-076C-SH has a 76 V standoff voltage.

Pricing and Availability
As a pricing reference, the Bourns® models PTVS15-058C-SH and PTVS15-076C-SH are priced at $19.70 each in 10 piece quantities and $17.50 each in 500 piece quantities respectively. Both models are available now. For additional product specifications, please go to: www.bourns.com/data/global/pdfs/PTVS15-SH.pdf.

RIVERSIDE, Calif., January 15, 2014 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that it has released new product options to its industry-leading line of Model 95 Premium Guitar Potentiometers. Bourns developed this specialty line of potentiometers in response to customer requests for additional taper and resistance value options that help improve the sound quality, reliability and longevity in electric and bass guitars. The four new guitar potentiometer options from Bourns are being released in tandem with the upcoming NAMM Show, January 23-26, 2014 in Anaheim, California.

“Bourns continues to introduce new product options that help our customers get the highest quality out of their guitars and associated professional audio equipment,” said Chuck Manzano, Pro Audio Application Engineer at Bourns, Inc. “We have an ongoing commitment to provide a variety of options for both guitar designers (luthiers) and those guitarists who customize their guitars in search of the right tone. We are thrilled to provide our customers with the highly-requested 300 ohm resistance value, which is a long-time standard value used by one of the top U.S. guitar manufacturers.”

Bourns’ new selection of linear tapers and resistance values allow for a slower gain on volume controls, and enable enhanced adjustability of tone controls. In addition, the superior design qualities of Bourns’ long bushing potentiometers mean they are compatible for use in solid body guitars as well as in all types of electric and bass guitars. As with the complete line of Bourns Model 95 Premium Guitar potentiometers, these new options feature conductive polymer elements and multi-finger contact springs for low noise/impedance, long rotational life and dust protection for ease of maintenance, and smooth rotational operation for the discerning guitarist.

The four new configurations for the Bourns® Model 95 premium guitar potentiometer complement the variety of hand crafted parts and options already available:

Part Number Taper Shaft Bushing Resistance Value (kΩ)
