GUS-QS0B-02-7870-CB Description

The GUS-QS0B-02-7870-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 787Ω resistance value per resistor with an ultra-tight 0.25% tolerance and a low ±50ppm/°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 a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The thin-film technology provides superior accuracy and long-term reliability compared to thick-film alternatives.

GUS-QS0B-02-7870-CB Features

• Precision Thin Film: Delivers ±0.25% tolerance and ±50ppm/°C TCR for critical analog circuits.
• Robust Construction: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm height/length tolerances ensures consistent mounting.
• High Power Handling: 1W total dissipation (0.05W per resistor) at 125°C maximum temperature.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm pitch simplify pick-and-place processes.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
• Non-RoHS Compliant: Suitable for legacy or exempted systems.

GUS-QS0B-02-7870-CB Applications

This resistor network excels in:

• Precision Voltage Dividers: Used in DAQ systems and sensor interfaces due to its low TCR and tight tolerance.
