GQ0A012002BBT Description

The GQ0A012002BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter-Small Outline Package) device integrates 10 isolated 20KΩ resistors with an exceptional tolerance of ±0.1% and a low temperature coefficient of ±100ppm/°C, ensuring stability across a wide operating range of 70°C to 125°C. Encased in a robust ceramic package, it offers superior thermal performance and mechanical durability, making it ideal for harsh environments. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision analog circuits where accuracy and reliability are critical.

GQ0A012002BBT Features

• High Precision: ±0.1% tolerance and ±100ppm/°C TCR for consistent performance in temperature-varying conditions.
• Robust Construction: Ceramic case and gull-wing termination ensure durability and ease of surface-mount assembly.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk, ideal for multi-channel systems.
• Compact Form Factor: 8.66mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm height/length) save PCB space.
• Wide Operating Range: Rated for 125°C maximum temperature, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
