GQ8A028062JBT Description

The GQ8A028062JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features an 80.6K Ohm resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, 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.

GQ8A028062JBT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and tight 5% tolerance for stable operation.
• Robust Construction: Ceramic case ensures thermal stability and mechanical strength, ideal for harsh environments.
• Compact & Efficient: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch maximizes space savings.
• Isolation-Centric Design: ISOL circuit configuration prevents crosstalk, critical for signal integrity in multi-channel systems.
• Wide Operating Range: Functions reliably from -70°C to +125°C, with derated power up to 125°C.

GQ8A028062JBT Applications

This resistor network excels in:

• Industrial Control Systems: Isolated signal conditioning and voltage division in PLCs and sensors.
• Medical Electronics: Precision analog circuits where drift and noise must be minimized.
• Telecommunications: Impedance matching and termination in high-frequency RF modules.
• Automotive (Non-Automotive Rated): Auxiliary circuits in infotainment or lighting systems (note: not PPAP/automotive certified).
• Test & Measurement Equipment: Calibration networks requiring long-term stability.

Conclusion of GQ8A028062JBT

The GQ8A028062JBT stands out for its combination of precision, compactness, and isolation capabilities, making it a superior choice over generic thick-film networks. While not RoHS-compliant or automotive-rated, its ceramic construction and thin-film technology ensure reliability in professional and industrial settings. Engineers will appreciate its balance of power handling, thermal performance, and space efficiency, particularly in designs demanding high-density, low-drift resistor arrays.
