GUS-QS0B-03-4302-FF Description

The GUS-QS0B-03-4302-FF from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 43K Ohm resistance value with a tight 1% 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 power dissipation (1W total, 0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits.

GUS-QS0B-03-4302-FF Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in varying thermal conditions.
• High-Density Integration: 19 resistors in a 6.02mm x 8.66mm QSOP package optimize PCB space.
• Robust Power Handling: 1W total power rating (1/20W per resistor) with derated operation up to 125°C.
• Automated Assembly-Friendly: Gull-wing SMD terminations and 0.64mm pitch ensure compatibility with high-speed pick-and-place processes.
• Non-Automotive, Non-PPAP: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
