GS4B024221DT Description

The GS4B024221DT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for surface-mount applications, it features a 4.22KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. The ceramic-based thin-film technology ensures stability across a wide temperature range (70°C to 125°C) while delivering 0.05W (1/20W) power dissipation per resistor and 0.4W total power rating. Its 100V maximum voltage rating and gull-wing termination make it suitable for high-reliability circuits.

GS4B024221DT Features

• Precision Network: 7 bussed resistors with 4.22KΩ ±0.5% absolute tolerance.
• Robust Construction: Ceramic SOIC case with rectangular package (4.9mm x 5.99mm x 1.45mm) and ±0.1mm dimensional tolerances.
• Thermal Performance: Thin-film technology ensures low drift (±50ppm/°C) up to 125°C.
• High Voltage Handling: 100V rating per resistor, ideal for industrial and automotive-derivative designs.
• Automation-Friendly: Gull-wing leads (1.27mm pitch) for reliable SMT assembly.

GS4B024221DT Applications

This resistor network excels in precision analog circuits, voltage dividers, and sensor signal conditioning where tight tolerances and thermal stability are critical. Its bussed configuration simplifies PCB layout in multi-channel systems, such as:

• Industrial PLCs requiring stable reference voltages.
• Medical instrumentation for low-noise signal paths.
• Automotive subsystems (non-AECQ, per PPAP "No" status).
• Test & measurement equipment demanding repeatable performance.

Conclusion of GS4B024221DT

The GS4B024221DT combines precision, power efficiency, and compactness in a ceramic SOIC package, making it a standout choice for engineers prioritizing tolerance stability and thermal resilience. While not automotive-qualified, its 100V rating and thin-film reliability suit harsh-environment applications. For designs needing bussed networks with sub-1% error, this model offers a compelling balance of performance and cost.
