Vishay PLTT thin film resistor

Vishay has introduced a 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 h, the resistor is optimised 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.

The device has a range from 250Ω to 50 kΩ, with non-standard values available. It features low noise of <-35 dB, low-voltage coefficients of 0.1 ppm/V, a power rating of 250 mW and a 75 to 200 V working voltage range.
