GQ8A026191JBT Description

The GQ8A026191JBT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 6.19KΩ resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C operating range. The device features 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Rated for 0.75W (3/4W) total power and 100V maximum voltage, it is ideal for isolation (ISOL circuit designator) and signal conditioning in demanding environments.

GQ8A026191JBT Features

• Thin-film technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• Ceramic case: Enhances thermal stability and durability in high-temperature applications.
• Isolated resistors (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Gull-wing termination: Ensures robust solder joints and compatibility with automated PCB assembly.
• Wide temperature range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• Precision tolerances: Tight ±0.1mm height/length tolerances for consistent placement.

GQ8A026191JBT Applications

This resistor network excels in:

• Industrial automation: Signal isolation in PLCs and sensor interfaces.
• Medical electronics: Precision analog circuits in diagnostic equipment.
• Telecommunications: Impedance matching and filtering in RF modules.
• Automotive (non-AECQ): Engine control units (ECUs) where high-temperature stability is critical.
• Test & measurement: Calibration circuits requiring low drift over temperature.

Conclusion of GQ8A026191JBT

The GQ8A026191JBT stands out for its ceramic-encapsulated design, thin-film precision, and isolated resistor configuration, making it a robust choice for high-reliability applications.
