GQ0A027870DT Description

The GQ0A027870DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 10-resistor array features a 787 Ω resistance value with an ultra-tight 0.5% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The 20-pin gull-wing SMD termination ensures robust surface-mount compatibility, while its isolated (ISOL) circuit design minimizes crosstalk in multi-channel systems.

GQ0A027870DT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Combines thermal resilience with compact dimensions (8.66mm × 6.02mm × 1.47mm).
