GQ8A0166R5GDT Description

The GQ8A0166R5GDT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP ceramic package, it offers 66.5Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design allows each resistor to function independently, making it ideal for complex circuitry. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this network balances power handling with compact surface-mount (SMD) gull-wing termination. Its ceramic case ensures durability and thermal performance, while the QSOP package (4.9mm x 6.02mm x 1.47mm) suits space-constrained designs.

GQ8A0166R5GDT Features

• Precision Thin Film Technology: Delivers stable, low-noise performance with ±100ppm/°C TCR.
• High Power Density: 0.75W total power (0.1W per resistor) in a compact QSOP-16 footprint.
• Isolated Resistors: 8 independent 66.5Ω resistors (ISOL design) for flexible circuit integration.
• Robust Construction: Ceramic package enhances thermal management and mechanical strength.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for automated PCB assembly.
• Non-Automotive: Suitable for industrial, telecom, and instrumentation (PPAP not required).

GQ8A0166R5GDT Applications

• Signal Conditioning: Precision voltage dividers or pull-up/down networks in data acquisition systems.
• Medical Electronics: Isolated resistor networks for patient monitoring equipment.
• Test & Measurement: High-stability reference circuits in calibration instruments.
• Telecom Infrastructure: Impedance matching in RF modules and baseband PCBs.
• Industrial Controls: Robust solution for PLC I/O modules exposed to wide temperature swings.

Conclusion of GQ8A0166R5GDT

The GQ8A0166R5GDT excels in applications demanding precision, isolation, and compact power handling. Its ceramic QSOP package, thin film technology, and 2% tolerance make it a superior choice over bulkier or less stable alternatives like thick-film networks. While not RoHS-compliant, it remains a go-to for non-consumer, high-reliability systems where performance outweighs regulatory constraints. Engineers will appreciate its balance of density, accuracy, and thermal resilience in critical analog designs.
