GQ8A034121FAT Description

The GQ8A034121FAT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 4.12KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The device features 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Its isolated (ISOL) circuit design allows independent resistor operation, making it ideal for signal conditioning and impedance matching. Rated for 0.1W per resistor (0.75W total) and 100V maximum voltage, it balances power handling with precision.
