GQ8A038872CBT Description

The GQ8A038872CBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 88.7kΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design (4.9mm x 6.02mm footprint) facilitate compact PCB integration.

GQ8A038872CBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital interfaces.
• Isolation-Centric Design: Ideal for ISOL (isolation) circuit applications, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal performance and mechanical durability vs. plastic alternatives.
• High Power Density: 0.75W total dissipation in a compact QSOP form factor, outperforming similar networks with lower ratings.
• Strict Tolerances: ±0.25% resistance accuracy and ±0.1mm height tolerance ensure consistent performance in automated assembly.
• Non-Automotive/Non-RoHS: Suitable for industrial and commercial applications where RoHS compliance is not mandated.

GQ8A038872CBT Applications

• Medical Isolation Circuits: Patient monitoring equipment requiring high-voltage isolation.
