RNCS Series
Stackpole Electronics, Inc.
Anti-Corrosive Tantalum Nitride Replacement Resistor Resistive Product Solutions
Features:
Special Passivation for moisture sensitive applications
Absolute TCRs to 25 ppm/C
Available in industry standard sizes from 0402 to 2512
Resistance range from 10 to 1M
Test proven immunity to humidity and moisture corrosion
Absolute tolerances to 0.1%
Ideal replacement for costly Tantalum Nitride resistors
RoHS compliant / lead-free
The RNCS series employs a special manufacturing process to ensure high precision, ultra stable performance, and long
life in the harshest environments. In moisture comparison testing, the RNCS series outperformed Nichrome Chip
Resistors and demonstrated the anti-corrosive claims characterized by Tantalum Nitride resistor products.
