Stackpole’s AEC qualified RTAN series utilises tantalum nitride technology provide moisture proof precision chip resistor performance. Stackpole has recently expanded the available tolerances to include 0.05%, and TCR options now include 10 ppm/ºC.
Electronics are being used in a wide range of devices and environments. As a result, component performance under environmental stress is more critical. When the application requires both environmental stability and high precision, resistor options become very limited.
Nichrome-based thin film resistors have excellent electrical performance and stability but can experience corrosion under prolonged exposure to high moisture environments. Stackpole’s AEC-Q200 qualified RTAN series utilizes tantalum nitride technology to provide moisture proof precision chip resistor performance.
The RTAN film passes biased humidity testing at 85ºC,85% relative humidity, and 10% bias with very little shift in resistance. Stackpole has recently expanded the available tolerances to include 0.05%, and TCR options now include 10 ppm/ºC.
This expansion enables the use of the RTAN for a wider variety of precision application requirements such as:
- test equipment
- industrial controls
- portable communications diagnostic equipment
- portable medical devices.
Pricing for the RTAN depends on size and tolerance but ranges from $0.15 to $0.65 in full reel quantities.
