GS4A022551DBT Description

The GS4A022551DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 2.55KΩ resistance and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for stable performance across a wide temperature range (70°C to 125°C). Encased in a rectangular ceramic SOIC package, it offers 100V maximum voltage rating and gull-wing termination for reliable surface-mount assembly.

GS4A022551DBT Features

• Precision Performance: ±0.5% tolerance and ±0.1% ratio tolerance for critical analog circuits.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Isolated Design: Four independent resistors (isolated elements) reduce crosstalk in high-density layouts.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Surface-Mount Ready: 1.27mm terminal pitch and SOIC package (4.9mm x 5.99mm x 1.45mm) for compact PCB integration.
• Low TCR: ±50ppm/°C minimizes resistance drift under thermal stress.

GS4A022551DBT Applications

Ideal for precision analog and mixed-signal systems, including:

• Industrial Control Systems: Signal conditioning, voltage dividers, and feedback networks.
• Medical Electronics: High-accuracy sensor interfaces and instrumentation amplifiers.
• Automotive (Non-Automotive Rated): Engine control units (ECUs) and infotainment systems (where PPAP is not required).
• Test & Measurement Equipment: Calibration circuits and reference voltage networks.
• Telecommunications: Line termination and impedance matching in RF modules.

Conclusion of GS4A022551DBT

The GS4A022551DBT stands out for its precision, isolation, and ceramic-based reliability, making it a superior choice for applications demanding tight tolerances and thermal stability. While not PPAP or automotive-qualified, its thin-film technology and low TCR ensure consistent performance in industrial, medical, and telecom environments. Its compact SOIC footprint further enhances its suitability for space-constrained designs.
