FEATURES
•Unique passivation coating eliminates moisture concerns and allows for use in applications traditionally
restricted to tantalum nitride
• Outperforms other thin film resistor materials providing excellent tolerances, ratio matching,
temperature coefficient, and temperature tracking
• Improved performance over silicon substrates in stray capacitance, frequency response and stability
