GQCA027680BBT Description

The GQCA027680BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter-Small Outline Package) device features 12 isolated resistors, each with a 768Ω resistance value and an ultra-tight 0.1% tolerance. Encased in a ceramic package, it offers excellent thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) provides space efficiency for compact designs.

GQCA027680BBT Features

• High Precision: 0.1% tolerance and ±50ppm/°C TCR ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Resistors: 12 individually isolated resistors (designated as ISOL) prevent crosstalk in sensitive circuits.
• Space-Saving Design: QSOP package (6.02mm depth, 1.47mm height) optimizes PCB real estate.
• Reliable Termination: Gull-wing leads (0.64mm pitch) ensure secure SMD soldering.
• Wide Operating Range: -70°C to +125°C derated power range suits industrial and automotive-grade applications (though non-PPAP and non-automotive certified).

GQCA027680BBT Applications

This resistor network is ideal for:

• Precision voltage dividers in instrumentation and test equipment.
• Signal conditioning circuits for ADCs/DACs in data acquisition systems.
• Feedback networks in op-amp and comparator circuits requiring low drift.
• Medical electronics where stable resistance values are critical.
• Industrial control systems demanding high reliability under thermal stress.
