GUS-QS0B-03-2430-C Description

The GUS-QS0B-03-2430-C is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 19-resistor array features a 243Ω resistance value with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 1W total power rating (0.05W per resistor), making it ideal for space-constrained designs requiring high accuracy and reliability.

GUS-QS0B-03-2430-C Features

• Precision Thin Film Technology: Delivers superior stability, low noise, and minimal drift over time.
• High Power Density: 1W total dissipation (1/20W per resistor) in a miniature QSOP package.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.
• Robust Construction: Rectangular QSOP case with ±0.1mm height/length tolerances for consistent PCB mounting.
• Automotive-Grade Alternatives: While not PPAP-certified, its 125°C max operating temperature suits harsh environments.
