GQ8A0137R4JDT Description

The GQ8A0137R4JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 8-resistor isolated network features a 37.4Ω resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (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 demanding circuit designs. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances versatility in high-voltage environments.

GQ8A0137R4JDT Features

• High Precision: Thin-film technology ensures low noise and stable performance.
• Robust Construction: Ceramic case provides excellent thermal and mechanical stability.
• Isolated Design (ISOL): Each resistor is electrically independent, ideal for multi-channel applications.
• Compact Footprint: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its durability suits industrial and telecom applications.
