GQ8A017870JBT Description

The GQ8A017870JBT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 787Ω resistance 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). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining isolation between resistors (denoted by the ISOL circuit designator). The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, making it suitable for automated assembly processes.

GQ8A017870JBT Features

• High Reliability: Ceramic case and thin film technology provide excellent thermal stability and long-term durability.
• Precision Performance: Tight tolerance (±5%) and low TCR (±100ppm/°C) ensure consistent performance in varying environments.
• Compact Design: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) dimensions with ±0.1mm height tolerance enable high-density PCB layouts.
• Isolated Resistors: Independent resistors (ISOL configuration) prevent cross-talk, ideal for signal conditioning and voltage division.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and automotive (non-AECQ) applications.

GQ8A017870JBT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in analog circuits.
• Industrial Controls: Stable resistance for PLCs, sensors, and instrumentation requiring thermal resilience.
• Power Management: Load balancing and current limiting in power supplies (derated at high temps).
• Test & Measurement Equipment: Low-noise, stable resistance for calibration and reference circuits.
• Non-Automotive Embedded Systems: Where EU RoHS compliance is not mandatory but reliability is critical.

Conclusion of GQ8A017870JBT

The GQ8A017870JBT stands out for its ceramic-encased isolation, thin-film accuracy, and compact SMD footprint, making it a superior choice for engineers prioritizing thermal performance and space efficiency. While not PPAP or automotive-grade, its 125°C operational limit and 0.75W power handling make it ideal for industrial, telecom, and precision electronics where consistent resistance under thermal stress is paramount. Its tube packaging ensures safe handling and storage for high-volume production.
