GUS-QS0B-03-5230-GG Description

The GUS-QS0B-03-5230-GG from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 523Ω resistance value per resistor with a tight 2% 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 compact 20-pin QSOP package with gull-wing terminations, it offers excellent space efficiency and reliability for densely populated PCBs. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits requiring consistent signal integrity.

GUS-QS0B-03-5230-GG Features

• Thin-film technology: Delivers superior accuracy, low noise, and long-term stability.
• High-density integration: 19 resistors in a 6.02mm x 8.66mm footprint, ideal for space-constrained designs.
• Robust construction: QSOP package with ±0.1mm height/length tolerances ensures mechanical reliability.
• Wide temperature range: Operates reliably from -55°C to 125°C (derated power up to 125°C).
• Automotive-grade alternatives: While this variant is not PPAP or automotive-qualified, its performance aligns with industrial standards.
• Non-RoHS compliant: Suitable for legacy or exempted applications requiring specific material properties.
