GQCA033301BBT Description

The GQCA033301BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated 3.3KΩ resistors with a 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 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.

GQCA033301BBT Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Surface-Mount Compatibility: Gull-wing termination and 0.64mm pitch enable compact PCB layouts.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C) for industrial and automotive-grade reliability.
• Low Noise: Thin-film technology reduces parasitic effects, ideal for signal conditioning and filtering.
