GQ8A0232R4FT Description

The GQ8A0232R4FT from TT Electronics/IRC is a high-precision, surface-mount thin-film resistor network designed for isolation (ISOL) circuit applications. This 16-pin QSOP-packaged device integrates eight 32.4Ω resistors with a tight tolerance of ±1% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. The ceramic case construction enhances thermal stability and durability, while the gull-wing termination facilitates reliable PCB mounting. With a derated power handling of 0.75W (3/4W) and a maximum voltage rating of 100V, this network is engineered for demanding environments.

GQ8A0232R4FT Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±50ppm/°C) for critical signal conditioning.
• Robust Ceramic Package: Ensures mechanical strength and thermal dissipation in high-temperature applications.
• Isolated Resistor Design (ISOL): Each of the eight 32.4Ω resistors operates independently, ideal for isolation or pull-up/down tasks.
• High Power Density: 0.1W per resistor (0.75W total) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Surface-Mount Gull Wing Terminals: Compatible with automated assembly processes, featuring a 0.64mm pitch for high-density layouts.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.
