GQ0A021431BBT Description

The GQ0A021431BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stability. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 1.43KΩ resistance value and an exceptional ±0.1% tolerance. Encased in a ceramic package, it offers superior thermal performance, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A021431BBT Features

• High Precision: ±0.1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal stability and mechanical durability.
• Isolated Resistors: 10 independent resistors (ISOL designator) prevent crosstalk in multi-channel systems.
• Compact & Reliable: QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for high-density PCB layouts.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power handling.
• Industry-Standard Compliance: HTS 8533.21.00.20, ECCN EAR99, though non-RoHS (note for restricted applications).
