RNCS/RNCH Series
Anti-Corrosive Tantalum Nitride Replac ement Resistor
Stackpole Electronics, I nc.
Resistive Product Solutions
Features:
• Special Passivation for moisture sensitive applications
• Absolute TCR’s to 15 ppm/ºC
• Test proven immunity to humidity and moisture corrosion
• Absolute tolerances to 0.1%
• Ideal replacement for costly Tantalum Nitride resistors
• Qualified to AEC-Q200
• E196 values are not marked
• RoHS compliant / lead-free
The RNCS/RNCH series employs a special manufacturing process to ensure high power, high precision, ultra stable
performance, and long life in the harshest environments. In moisture comparison testing, the RNCS/RNCH series
outperformed conventionally passivated Nichrome chip resistors and demonstrated the anti-
corrosive claims
characterized by Tantalum Nitride resistor produc ts .

used in th e electronics industr y is very com plex, we work closely with our o wn suppliers to verify to the extent possible
that the materials and products we supply do not contain metals sourced from this conflict region. As such, we are in
compliance with the requirements of Dodd-Frank Act regarding Conflict Minerals.
