Vishay has introduced a series of dual-inline thin film resistor networks with an operating temperature range of -55 to + 215°C.
Providing nearly a 100°C extension in operating temperature over traditional thin film chip resistors, the HTRN series features low absolute TCR of ± 25 ppm/ºC, TCR tracking of 5 ppm/ºC and tight ratio tolerances to ± 0.05%.
Featuring a rugged, moulded 50 mil pitch construction with no internal solder, the series has four isolated resistors with a wide range of 1 - 100 kΩ per resistor, with divider ratios from 2:1 to 100:1.
The devices feature very low noise of <-35 dB, low voltage coefficients of 0.1 ppm/V and a power rating of 100 mW per element (400 mW per package).
With stable film and performance characteristics of 500 ppm and 25% rated power at +215°C for 2000 hours, the resistors are optimised for the low-noise, single-signal processing required to compensate for low offset and temperature drift in high temperature environments, including downhole applications, motor vehicle under-the-bonnet applications, high-precision oil and gas exploration, aerospace engine control, telecommunications and industrial equipment.
Offering a 1.73 mm maximum seated height, the devices have a ceramic substrate and 10 - 20 μin gold terminations for high-temperature HMP soldering. The resistor networks are RoHS compliant, halogen-free and flame-resistant.
