GS4A021962DBT Description

The GS4A021962DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 19.6 kΩ and an absolute tolerance of ±0.5%. Its ±50 ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of 70°C to 125°C, making it suitable for precision analog and digital circuits. The SOIC-C series construction provides excellent thermal and mechanical stability, while the gull-wing termination facilitates reliable surface-mount assembly.

GS4A021962DBT Features

• High Precision: Tight tolerance (±0.5%) and low TCR (±50 ppm/°C) for stable performance.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Isolated Resistors: Four independent resistors (19.6 kΩ each) for flexible circuit design.
• Surface-Mount Ready: Gull-wing terminals and SOIC package (4.9 mm × 5.99 mm × 1.45 mm) for easy PCB integration.
• Wide Operating Range: Derated power up to 125°C, with a maximum voltage rating of 100 V.
• Low Power Dissipation: 0.1 W per resistor (0.4 W total) for energy-efficient designs.

GS4A021962DBT Applications

This resistor network is ideal for:

• Precision voltage dividers in instrumentation and sensor interfaces.
• Signal conditioning circuits requiring stable resistance ratios (±0.1% ratio tolerance).
• Industrial control systems where thermal stability and reliability are critical.
• Medical electronics demanding low drift and high accuracy.
• Automotive test systems (though not automotive-qualified, its performance suits prototyping).

Conclusion of GS4A021962DBT

The GS4A021962DBT excels in applications requiring high precision, thermal stability, and compact packaging. Its ceramic construction, isolated resistors, and low TCR make it a superior choice over standard thick-film networks. While not PPAP or automotive-qualified, its performance suits industrial, medical, and test equipment where reliability is paramount. Engineers will appreciate its balance of accuracy, power handling, and mechanical robustness in space-constrained designs.
