Tantalum nitride anti-moisture resistors on short lead times

Current market conditions are making it challenging to find common components such as precision chip resistors. If the application requires robust stability and moisture withstanding, tantalum nitride technology is a great solution. Unfortunately, tantalum nitride resistors can have long lead times and aren’t typically available from stock.


Stackpole’s RTAN series is an AEC compliant precision chip resistor with popular resistance values available from stock in the 0805 and 1206 sizes. Lead times are typically 12 to 16- weeks depending on chip size.


The RTAN’s sputtered resistive element is made from tantalum nitride, providing a resistor with high stability and reliability that is also impervious to moisture. The series suits harsh environmental conditions, especially where high humidity or moisture is a concern.


Applications include instrumentation, aerospace, test equipment, industrial controls, portable communications diagnostic equipment and portable medical devices.
