RIVERSIDE, Calif., April 14, 2015 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced new high voltage thick film chip resistor devices optimized for high voltage and consumer electronics applications. The new Bourns® Model CHV series is available in five footprint options from 0603 (1608 Metric) up to 2512 (6432 Metric), and is designed to operate with much higher voltages of 200 V on the 0603 size and 3 kV on the 2512 size. These UL 1676 listed resistors are manufactured using a robust thick film element printed onto a ceramic substrate. The new family strengthens the company’s existing broad line of surface mount chip resistors and complements its other circuit conditioning components including power inductors, rectifier diodes and Zener diodes.

“Bourns’ next-generation chip resistor family is designed to support our customers’ higher voltage, rugged design and varied footprint option needs,” said Brian Ahearne, product line manager at Bourns, Inc. “Bourns is known as a pioneer in the development of thick film resistors, and this latest series leverages the company’s extensive engineering, manufacturing and quality assurance experience.”

Pricing and Availability
Bourns® CHV series of chip resistors are RoHS compliant* and available now. As a pricing reference, the Model CHV0603-FX is priced at $ 0.147 each in 5000 piece quantities. For more information, please see the Bourns® Chip Resistors products page.

RIVERSIDE, Calif., April 7, 2015 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the availability of two new high voltage Power Transient Voltage Suppressor (PTVS) devices, further expanding the line offered with SMD packaging to a total of 20 products. Featuring bidirectional port protection of 58 and 76 volts, the new PTVS devices meet stringent IEC 61000-4-5 8/20 μs current surge requirements in high-power DC clamping applications that include AC/DC power supplies exposed in outdoor environments and wireless base stations. Bourns designed its PTVS line with silicon-based technology that provides numerous advantages over typical competing MOV technology including lower clamping voltage under surge, greater performance stability and increased reliability.

Designs benefit from the new devices’ SMD package, which delivers a reduction in peak clamping voltage compared to an equivalent through-hole device because of its lower lead inductance. The result is decreased electrical stress on the protected circuitry. SMD packaging can also reduce costs by eliminating the extra manufacturing step in designs where the PTVS diode is the only through-hole component on the printed circuit board. In addition, these new PTVS products offer an excellent surge response versus temperature; the typical maximum surge current at 150 °C exceeds 70 percent of their rated value at 25 °C.

Bourns® Model Repetitive Standoff Voltage – VWM Peak Current Rating per 8/20 μs – IPPM
PTVS6-058C-SH 58 V 6kA
PTVS6-076C-SH 76 V 6kA

“Giving our customers a broader range of repetitive standoff voltage options enables them to select the right PTVS device specifically matched to their protection design needs without interfering with normal power line operations. Bourns’ PTVS solutions help address power supply uptime and maintenance cost concerns in applications that must operate outdoors or in harsh environmental conditions,” said Ben Huang, product line manager at Bourns, Inc.

Pricing and Availability
Bourns’® latest PTVS products are RoHS compliant* and available now. As a pricing reference, the Bourns® Model PTVS6-058C-SH is priced at $ 21.56 each and Model PTVS6-076C-SH is priced at $23.51 each both in 20-piece quantities. For more information, please see the Bourns® Power TVS products page.
