GQ0A025492DBT Description

The GQ0A025492DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 54.9kΩ resistance value and an exceptional ±0.5% tolerance. The ceramic case ensures robust thermal and mechanical stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a ±50ppm/°C temperature coefficient, it delivers consistent performance across a wide operating range of -70°C to +125°C. The 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for precision analog and mixed-signal circuits.

GQ0A025492DBT Features

• Precision Thin Film Technology: Ensures low noise, high stability, and tight resistance tolerances (±0.5%).
• Isolated Resistor Network: 10 independent resistors in a QSOP-20 package, ideal for signal isolation.
• High-Temperature Performance: Operates reliably up to 125°C with derated power capabilities.
