Vishay Intertechnology’s New PLTT Precision Low-TCR, High-Temperature Thin Film Resistor

29 MARCH 2011

Vishay Intertechnology, Inc. introduced a new precision low-TCR thin film resistor offering a wide operating temperature range of – 55 degree C to + 215 degree C. Providing nearly a 100 ?C extension in operating temperature range over traditional thin film chip resistors, the PLTT features a low standard TCR of ± 5 ppm/degree C and tolerances down to ± 0.02%.
With stable film and performance characteristics of 500 ppm at + 215 degree C for 2000 hours, the resistor released today is optimized for the low-noise, single-signal processing required to compensate for low offset and temperature drift in high-temperature environments, including down-hole applications, high-precision oil and gas exploration, and telecommunications and industrial equipment.
Offered in the 0805 case size, the PLTT resistor offers a resistance range from 250Ohm to 50 kOhm, with non-standard values available. The device features very low noise of < - 35 dB, low voltage coefficients of 0.1 ppm/V, a power rating of 250 mW, and a 75 V to 200 V working voltage range. The PLTT features a high-purity ceramic substrate, 10 μin gold terminations over nickel barrier for high-temperature HMP soldering, and corrosion-resistant special passivation method (SPM) enhancement. The resistor is compliant with RoHS Directive 2002/95/EC, halogen-free according to the IEC 61249-2-21 definition, and flame-resistant in accordance to UL 94 V-0. Samples and production quantities of the PLTT resistor are available now, with lead times of 10 to 12 weeks for standard orders.
