GQ8A012201GT Description

The GQ8A012201GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 2.2K Ohm resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination facilitates easy surface-mount (SMD) assembly. With a maximum voltage rating of 100V and a power rating of 0.75W (3/4W), this network balances compactness with robust power handling.

GQ8A012201GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical circuits.
• Ceramic QSOP Package: Enhances thermal performance and mechanical strength.
• Isolated Resistor Design (ISOL): Prevents signal interference between channels.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• High Power Density: 0.1W per resistor (total 0.75W) in a compact 4.9mm x 6.02mm x 1.47mm footprint.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with automated assembly.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation use.
