GQ8B027152CAT Description

The GQ8B027152CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 71.5K Ohm resistance value, offering a tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient. Encased in a ceramic package, it ensures superior thermal stability and durability. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand a maximum voltage of 100V. With a 0.75W (3/4W) total power rating (0.05W per resistor), it is ideal for precision analog and digital circuits requiring stable performance under varying conditions.

GQ8B027152CAT Features

• High Precision: 0.25% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal management and long-term reliability.
• Space-Efficient: QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing terminations enables compact surface-mount (SMD) designs.
• Wide Operating Range: Supports -55°C to +125°C (full range) with derated power up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its performance rivals such variants.

GQ8B027152CAT Applications

• Precision Instrumentation: Ideal for DAQ systems, medical devices, and test equipment where accuracy is paramount.
• Industrial Controls: Suitable for PLC modules, sensor interfaces, and power management circuits due to its stability under thermal stress.
• Communications: Used in RF modules and signal conditioning networks where low TCR minimizes frequency drift.
• Aerospace & Defense: Non-compliant with EU RoHS, but applicable in niche military-grade hardware requiring ceramic encapsulation.

Conclusion of GQ8B027152CAT

The GQ8B027152CAT excels in high-reliability, precision applications where thermal performance, miniaturization, and electrical stability are critical. Its ceramic thin-film design and tight tolerances make it a standout choice over polymer-based or less stable networks. While not suited for automotive or RoHS-compliant projects, it remains a top-tier solution for industrial, aerospace, and instrumentation designs demanding uncompromising performance.
