Stackpole Electronics, Inc.
Resistive Product Solutions
Special Passivation for moisture sensitive applications
Absolute TCR’s to ±25 ppm/ºC
Available in industry standard sizes from 0402 to 2512
E192 value is built to order with no part marking
Resistance range from 10Ω to 1MΩ
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.
