GQ8A033921GAT Description

The GQ8A033921GAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it features a 3.92KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration offers reliable surface-mount compatibility, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety and flexibility in complex layouts.

GQ8A033921GAT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog/digital systems.
• Robust Ceramic Package: Ensures thermal stability and mechanical durability in harsh environments.
• High-Density QSOP (6.02mm x 4.9mm): Saves PCB space while providing 16 gull-wing terminals for secure mounting.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision instrumentation.
• Non-Automotive, Non-PPAP: Ideal for industrial, telecom, and consumer electronics where PPAP compliance isn’t required.

GQ8A033921GAT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Isolation and impedance matching in data acquisition systems.
• Medical Equipment: Stable performance in patient monitoring devices and diagnostic tools.
• Telecom Infrastructure: High-frequency filtering and termination in base stations/routers.
• Test & Measurement: Calibration and reference circuits due to low TCR and tight tolerance.
• Industrial Controls: Durable operation in PLCs, motor drives, and power supplies.

Conclusion of GQ8A033921GAT

The GQ8A033921GAT combines precision, compactness, and reliability, making it a standout choice for engineers needing stable resistor networks in space-constrained, high-temperature, or noise-sensitive designs. Its ceramic construction, thin-film technology, and ISOL configuration provide distinct advantages over polymer-based or lower-tolerance alternatives. While not RoHS-compliant, it remains a robust solution for non-consumer applications demanding long-term performance under thermal and electrical stress.
