GQ8A034020JFT Description

The GQ8A034020JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor network features a 402Ω resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.1W (1/10W) power rating per resistor and a total power rating of 0.75W (3/4W), making it suitable for demanding circuit designs. The gull-wing termination and surface-mount (SMD) design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A034020JFT Features

• High Precision: Thin-film technology ensures low noise and excellent stability over time and temperature.
• Robust Construction: Ceramic case provides superior thermal and mechanical resilience compared to plastic alternatives.
• Compact & Durable: QSOP package (4.9mm x 6.02mm x 1.47mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained designs.
• Isolated Resistors: Circuit designator "ISOL" indicates independent resistors, ideal for signal isolation or multi-channel applications.
• Wide Operating Range: -55°C to +125°C (derated above 70°C) ensures reliability in harsh environments.
• Non-Automotive: Suitable for industrial, telecom, and instrumentation uses where PPAP compliance is not required.

GQ8A034020JFT Applications

• Signal Conditioning: Precision voltage dividers or feedback networks in op-amp circuits.
• Medical Electronics: Stable resistance for patient monitoring equipment where drift is critical.
• Test & Measurement: High-accuracy multichannel data acquisition systems.
• Telecom Infrastructure: Line termination or impedance matching in high-frequency PCBs.
• Industrial Controls: Isolated I/O modules requiring consistent performance under thermal stress.

Conclusion of GQ8A034020JFT

The GQ8A034020JFT stands out for its thin-film precision, ceramic ruggedness, and isolated resistor configuration, making it a superior choice for applications demanding thermal stability and compactness.
