GQ8A034752GBT Description

The GQ8A034752GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 47.5K Ohm resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GQ8A034752GBT Features

• High Precision: ±25ppm/°C TCR and 2% tolerance for consistent performance.
• Robust Construction: Ceramic case ensures thermal and mechanical reliability.
• Isolated Design (ISOL): Independent resistors reduce crosstalk in sensitive circuits.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power.
• Compact & Durable: 4.9mm x 6.02mm x 1.47mm dimensions with ±0.1mm length/height tolerances.
• Surface-Mount Ready: 0.64mm terminal pitch simplifies automated assembly.
