GQ8A012700BBT Description

The GQ8A012700BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 270Ω resistance value per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the isolated (ISOL) circuit configuration enhances signal integrity in multi-channel systems.

GQ8A012700BBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Robust construction with ±0.1mm length/height tolerances for consistent PCB alignment.
• High Power Density: 0.75W total rating in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Resistor Network (ISOL): Independent resistors minimize crosstalk in multi-signal paths.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• Automation-Friendly: 0.64mm terminal pitch and gull-wing leads optimize pick-and-place efficiency.
