RNCS Series — Anti-Corrosive Precision Thin Film Chip Resistors
Features
• Special passivation for moisture
sensitive applications
• Absolute TCR’s to ±25 ppm/°C
• Available in industry standard sizes
from 0201 to 2512
• Resistance range from 4.7Ω 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.
