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

Press release date: April 10, 2014

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="">

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="">

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.
