GQCB0128R0FT Description

The GQCB0128R0FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 28Ω resistance value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GQCB0128R0FT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• High-Density Integration: 23 resistors in a single QSOP package reduce component count and assembly complexity.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or Automotive qualified, its performance parallels higher-tier solutions.
