GS8A034021CT Description

The GS8A034021CT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 4.02KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, this ceramic-based thin-film network ensures exceptional stability across a wide temperature range (70°C to 125°C). Its 100V maximum voltage rating and 0.1W power rating per resistor (0.8W total) make it suitable for precision analog and digital circuits. The gull-wing termination and SOIC-C series ceramic case provide robust mechanical and thermal performance, ideal for harsh environments.

GS8A034021CT Features

• High Precision: ±0.25% absolute tolerance and ±25ppm/°C TCR for critical signal conditioning.
• Isolated Design: 8 independent resistors (non-bussed) for flexible circuit integration.
• Robust Construction: Ceramic substrate with thin-film technology ensures low noise and high reliability.
• Space-Efficient: Compact 9.91mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade prototypes (though not PPAP/automotive-certified).
• Non-RoHS: May be preferred for legacy or specialized applications requiring non-compliant materials.

GS8A034021CT Applications

• Precision Instrumentation: Voltage dividers, feedback networks in op-amp circuits.
• Medical Electronics: Patient monitoring systems where stability is critical.
• Industrial Controls: PLCs, sensor interfaces, and signal isolation.
• Telecom Infrastructure: Line termination, impedance matching in high-frequency modules.
• Test & Measurement Equipment: Calibration references due to low drift.

Conclusion of GS8A034021CT
