GQCA021373CBT Description

The GQCA021373CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP surface-mount device integrates 12 isolated resistors, each with a 137KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in circuit matching. Encased in a ceramic package, it delivers superior thermal stability with a ±50ppm/°C temperature coefficient and operates reliably across a -70°C to +125°C derated power range. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for precision analog and digital systems.

GQCA021373CBT Features

• High Precision: 0.25% tolerance and ±50ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Design: 12 resistors with ISOL (isolated) circuit designator, minimizing crosstalk in multi-channel applications.
• Surface-Mount Ready: Gull wing termination and QSOP package (8.66mm × 6.02mm × 1.47mm) enable compact PCB layouts.
• Wide Operating Range: -70°C to +125°C derated range, suitable for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 qualified).
