Vishay Offers New PLTT Precision Low-TCR, High-Temperature Thin Film Resistor
Vishay Intertechnology, Inc. introduced a new precision low-TCR thin film resistor offering a wide operating temperature range of - 55 to + 215°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/°C and tolerances down to ±0.02%.
With stable film and performance characteristics of 500 ppm at + 215°C for 2000 hours, the resistor 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 250Ω to 50kΩ, 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 250mW, and a 75 to 200V 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 of the PLTT resistor are available now. Production quantities will be available in Q1 2011, with lead times of 10 to 12 weeks for standard orders.
