GUS-QS0B-03-1242-JA Description

The GUS-QS0B-03-1242-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 12.4KΩ resistance value and a tight ±5% tolerance. It operates over a wide temperature range of -70°C to +125°C, with a derated power handling capability up to 125°C. The network delivers a total power rating of 1W (0.05W per resistor) and features a low ±25ppm/°C temperature coefficient, ensuring stable performance in demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances reliability in high-voltage circuits.

GUS-QS0B-03-1242-JA Features

• Compact & Robust: Housed in a rectangular QSOP package (8.66mm x 6.02mm x 1.47mm) with tight tolerances (±0.1mm height, ±0.2mm depth).
• Precision Thin Film: Delivers superior accuracy and stability compared to thick-film alternatives.
• High Power Density: 1W total dissipation (1/20W per resistor) in a small footprint.
• Wide Operating Range: Suitable for automotive-grade and industrial applications (though not PPAP or Automotive certified).
• Low TCR: ±25ppm/°C ensures minimal resistance drift across temperatures.
• Gull-Wing SMD Terminals: 0.64mm pitch for reliable soldering and compatibility with automated assembly.
