GQCA033090BBT Description

The GQCA033090BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 309Ω resistance value and an exceptional ±0.1% tolerance, ensuring minimal deviation in critical circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a temperature coefficient (TCR) of ±25ppm/°C over a wide operating range of -70°C to +125°C. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), this surface-mount network is ideal for precision analog and digital systems.

GQCA033090BBT Features

• High Precision: ±0.1% tolerance and ±25ppm/°C TCR ensure minimal drift in harsh environments.
• Robust Construction: Ceramic case and gull-wing termination provide mechanical strength and reliable solderability.
• Isolated Design: 12 resistors with independent isolation (ISOL) reduce crosstalk in sensitive circuits.
• Compact & Dense: 8.66mm × 6.02mm footprint with 0.64mm pitch enables high-density PCB layouts.
• Wide Temperature Range: Operates from -70°C to +125°C, derated for consistent performance.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
