GQ8A034302CBT Description

The GQ8A034302CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 43K Ohm resistance value with an exceptional ±0.25% tolerance and a low ±25ppm/°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 superior thermal stability and durability. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is ideal for precision analog and digital circuits requiring tight resistance matching and minimal drift.

GQ8A034302CBT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case and thin-film technology ensure reliability in harsh environments.
• Compact Design: 4.9mm x 6.02mm x 1.47mm dimensions with gull-wing SMD termination for space-constrained PCB layouts.
• Isolated Configuration: 8 independent resistors (ISOL circuit designator) for flexible circuit design.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Surface-Mount Ready: 0.64mm terminal pitch simplifies automated assembly.
