GQ8A039100BT

GQ8A039100BT Description

The GQ8A039100BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 910Ω resistance value with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable 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 per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance signal integrity in noise-sensitive environments.

GQ8A039100BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±25ppm/°C TCR for minimal drift.
• Robust Ceramic Package: Ensures thermal stability and mechanical durability in harsh conditions.
• High Power Handling: 0.75W total (0.1W per resistor) supports power-dense designs.
• Isolated Resistor Network (ISOL): Ideal for applications requiring signal separation or redundancy.
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions save board space.
• Gull-Wing SMD Termination: Compatible with automated assembly processes.
• Wide Operating Range: -55°C to +125°C (derated above 70°C) for industrial use.

GQ8A039100BT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces.
• Medical Electronics: Patient monitoring equipment requiring low drift and high isolation.
• Industrial Control Systems: PLCs, motor drives, and sensor conditioning with stringent tolerance requirements.
• Telecommunications: Signal isolation in RF and baseband processing.
• Automotive (Non-Automotive Grade): Test/measurement systems where EU RoHS non-compliance is acceptable.

Conclusion of GQ8A039100BT

The GQ8A039100BT combines precision, power efficiency, and isolation in a compact ceramic package, making it a standout choice for engineers designing critical analog systems. Its thin-film technology and tight tolerances outperform bulkier or less stable alternatives, while the QSOP-16 footprint aligns with space-constrained layouts. Though not PPAP or automotive-qualified, its 125°C rating and low TCR ensure reliability in industrial, medical, and telecom applications where accuracy and thermal performance are paramount.
