Precision Thin Film .300” Dual In-Line

Surface Mount Resistor Networks

• RoHS Compliant

• 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
