RNCS Series — Anti-Corrosive Precision Thin Film Chip Resistors
Features
• Special passivation for moisture
sensitive applications
• Ideal replacement for costly
Tantalum Nitride resistors
• Absolute TCR’s to ±5 ppm/°C
• Test proven immunity to humidity
and moisture corrosion
• Resistance range from 4.7Ω
to 1MΩ
• Available in industry standard
sizes from 0201 to 2512
• Absolute tolerances to 0.01%
• 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.
