GUS-QS8A-02-4221-CB Description

The GUS-QS8A-02-4221-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 4.22KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, derated up to 125°C. The network supports a maximum voltage rating of 100V and offers a total power dissipation of 0.75W (3/4W), with 0.1W (1/10W) per resistor, making it suitable for compact, high-density designs.

GUS-QS8A-02-4221-CB Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), with a 0.64mm terminal pitch for space-constrained PCBs.
• Robust Gull Wing Termination: Ensures reliable solder joints in automated SMT assembly.
• Extended Temperature Range: Operates reliably from -55°C to +125°C, with derated power up to 125°C.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and instrumentation applications.
