Tantalum nitride precision chip resistors add TCR capability
Stackpole's AEC qualified RTAN series utilises tantalum nitride technology to provide moisture proof precision chip resistor performance. The RTAN film passes biased humidity testing at 85oC, 85% relative humidity, and ten percent bias with very little shift in resistance.
The materials and design are such that the RTAN is resistant to sulfur contamination and will pass the industry standard sulfur test ANSI/EIA-977 (Method A) with minimal resistance shift. Stackpole has now 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. Those applications include instrumentation, aerospace, test equipment, industrial controls, portable communications diagnostic equipment, and portable medical devices.
Pricing for the RTAN depends on size and tolerance and ranges from $0.15 to $0.65 in full reel quantities.
