GS4A021240CT

GS4A021240CT Description

The GS4A021240CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 124Ω resistance with an exceptional ±0.25% absolute tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C), making it suitable for precision circuits. The SOIC-C series construction offers 0.1W (1/10W) power rating per resistor (0.4W total), 100V maximum voltage rating, and gull-wing termination for reliable surface-mount assembly. With EU RoHS non-compliance, it targets niche industrial applications where RoHS restrictions are not critical.

GS4A021240CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case with rectangular SOIC package (4.9mm × 5.99mm × 1.45mm) and ±0.1mm height tolerance.
• Isolated Design: Four independent resistors (HTS 8533.21.00.20) for flexible circuit integration.
• Wide Operating Range: -55°C to +125°C (derated above 70°C), ideal for harsh environments.
• Thin-Film Technology: Delivers low noise and high reliability.
• Automotive-Grade Alternative: While not PPAP/automotive-certified, its 125°C max temperature suits industrial analogs.

GS4A021240CT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks in op-amps.
• Signal Conditioning: Isolated resistor networks for sensors and ADCs.
• Industrial Controls: PLCs, power supplies, and test equipment requiring tight-tolerance components.
• Medical Devices: Diagnostic instruments where stability and accuracy are critical.
• Aerospace & Defense: Non-RoHS compliant variants for legacy systems.

Conclusion of GS4A021240CT

The GS4A021240CT excels in applications demanding high precision, thermal stability, and compact form factor. Its ceramic SOIC package and isolated thin-film resistors provide superior performance over standard arrays, particularly in industrial and instrumentation settings. While not automotive-qualified, its 125°C rating and 0.25% tolerance make it a cost-effective alternative for precision designs. Engineers will value its repeatability and mechanical robustness in surface-mount assemblies.
