Vishay Intertechnology Enhances PTN Series Precision Thin Film Chip Resistors
Devices Now Available With Lower Absolute TCR of ± 10 ppm/°C and Tighter Tolerances of ± 0.05 %
MALVERN, Pa. — Oct. 29, 2014 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that it has enhanced its PTN series of precision surface-mount thin film chip resistors with a lower absolute TCR of ± 10 ppm/°C and tighter tolerances to ± 0.05 %. Built using a self-passivated, moisture-resistant tantalum nitride resistive film technology, the Vishay Dale Thin Film devices offer high power ratings to 2 W over a wide temperature range of -55 °C to +155 °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 resistant to moisture at +85 °C, 85 % relative humidity and 10 % rated power; sulfur-resistant according to the ASTM B809-95 humid vapor test; and 100 % visually inspected per MIL-PRF-55342.
