Nichrome Resistor Networks
on Ceramic Substrates
NQS Series
• .025” Pitch DIP
• Precision Thin Film
• 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
