GUS-QS8A-03-1241-CB Description

The GUS-QS8A-03-1241-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.24KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solderability in automated PCB assembly.

GUS-QS8A-03-1241-CB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms similar networks in power density.
• Wide Temperature Range: Derated operation up to 125°C ensures reliability in industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Strict Tolerances: ±0.1mm height/length tolerances and ±0.2mm depth tolerance facilitate consistent PCB mounting.
