GQCB011621CAT Description

The GQCB011621CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 23 resistors with a 1.62KΩ resistance value, offering a tight 0.25% tolerance and a low ±100ppm/°C temperature coefficient for stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic QSOP package, this 24-pin gull-wing SMD component is optimized for surface-mount assembly, delivering 1W total power dissipation (0.05W per resistor). Its 100V maximum voltage rating and thin-film technology ensure reliability in precision circuits.

GQCB011621CAT Features

• High Precision: 0.25% tolerance and ±100ppm/°C TCR for minimal drift.
• Robust Construction: Ceramic case with gull-wing termination for mechanical and thermal stability.
• Compact Design: 8.66mm × 6.02mm × 1.47mm (L×D×H) with ±0.1mm dimensional tolerances.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial environments.
• Efficient Power Handling: 1W total dissipation (distributed across 23 resistors).
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its performance parallels higher-tier models.

GQCB011621CAT Applications
