GQ8A013482DBT Description

The GQ8A013482DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 34.8KΩ resistance value with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating 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 high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and instrumentation circuits.

GQ8A013482DBT Features

• Precision Thin-Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Case: Provides excellent thermal conductivity and mechanical robustness.
• Isolated Circuit Design (ISOL): Ensures independent resistor performance, critical for signal conditioning.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power handling.
• Automotive-Grade Alternatives: Though non-automotive (PPAP: No), its 125°C rating suits harsh environments.

GQ8A013482DBT Applications

• Industrial Control Systems: Precision voltage dividers, feedback networks in PLCs.
• Test & Measurement Equipment: High-accuracy signal attenuation/scaling.
• Medical Electronics: Isolated sensor interfaces due to low drift.
• Telecom Infrastructure: Line termination, impedance matching in RF modules.
• Power Management: Current sensing in DC-DC converters (up to 100V).

Conclusion of GQ8A013482DBT

The GQ8A013482DBT stands out for its combination of precision, power handling, and compactness, ideal for space-constrained, high-reliability designs. Its ceramic construction and thin-film technology outperform standard thick-film networks in stability and thermal performance. While not RoHS-compliant, it remains a top choice for non-consumer industrial applications requiring long-term accuracy under thermal stress. Engineers should consider this model for critical analog circuits where tolerance and temperature drift are paramount.
