April 11, 2014 - Offered in 13 case sizes from 0402 to 2512, PTN Series provides resistance values from 10 Ω to 3 MΩ. Surface mount devices are built using self-passivated, moisture-resistant tantalum nitride resistive film technology. Units offer low absolute TCR of 25 ppm/C and laser-trimmed tolerances down to 0.1% over operating temperature of -55 to +125C. Lead-free, halogen-free, and RoHS-compliant, resisters feature voltage ratings from 75–200 V and low noise of < -25 dB.

Vishay Intertechnology's PTN Series Precision Thin Film Chip Resistors Now Offer Power Rating to 2 W in 2512 Case Size

Devices Combine Moisture-Resistant Tantalum Nitride Film With Low TCR of 25 ppm/C and Tolerances Down to 0.1 %

MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has extended the power rating of PTN series precision surface-mount thin film chip resistors in the 2512 case size to 2 W. Built using a self-passivated, moisture-resistant tantalum nitride resistive film technology, the Vishay Dale Thin Film devices combine their high power rating with a low absolute TCR of 25 ppm/C and laser-trimmed tolerances down to 0.1 % over a wide temperature range of -55 C to +125 C.

The tantalum nitride resistive film of the PTN resistor assures a moisture-resistance level that exceeds MIL-PRF-55342 limits. This makes the devices ideal for use in low-noise, high-precision control systems for military, aerospace, telecommunications, and industrial applications where moisture during operation or long-term storage may be a concern.

The PTN series is offered in 13 case sizes from 0402 to 2512 and provides a wide range of resistance values from 10 Ω to 3 MΩ, with nonstandard values available. Featuring a high-purity ceramic substrate, the devices' wraparound terminations offer an adhesion layer covered with a nickel barrier and solder coating, and contribute resistance of < 10 mΩ. Epoxy-bondable and lead terminations are also available upon request.

In addition to power ratings from 50 mW to 2 W, the PTN series offers low noise of < -25 dB, low voltage coefficients of 0.1 ppm/V, and voltage ratings from 75 V to 200 V. The lead (Pb)-free devices are halogen-free, RoHS-compliant without exemptions, and conform to Vishay Green standards. The resistors are 100 % visually inspected per MIL-PRF-55342 and sulfur-resistant according to the ASTM B809-95 humid vapor test.

Samples and production quantities of the enhanced PTN series devices in the 2512 case size are available now, with lead times of eight to 10 weeks for large orders. Pricing for U.S. delivery in the 2512 case size starts at $1.00 per piece and varies by tolerance and quantity ordered.

Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets. Vishay's product innovations, successful acquisition strategy, and "one-stop shop" service have made it a global industry leader. Vishay can be found on the Internet at www.vishay.com.

more efficient resistors, please

Please, for high power resistors make something that converts the 'wasted' energy back into electric power.

Thank you.

Ray.
