GQ8A027501CAT Description

The GQ8A027501CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 7.5K Ohm resistance with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in sensitive applications.

GQ8A027501CAT Features

• Precision Thin Film Technology: Delivers ±50ppm/°C stability and 0.25% tolerance for critical analog/digital circuits.
• Robust Ceramic Package: Ensures durability and thermal performance in harsh environments.
• High Power Handling: 0.75W total (0.1W per resistor) with derating up to 125°C.
• Isolated Network (ISOL): Independent resistors prevent cross-talk, ideal for signal conditioning.
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• Gull-Wing SMD Termination: Compatible with automated assembly processes.
