GS4B024121BT Description

The GS4B024121BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stable performance. Housed in an 8-pin narrow SOIC package (SOIC-C series), this bussed network integrates 7 resistors with a common 4.12KΩ value, offering an absolute tolerance of ±0.1% and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures excellent stability and accuracy, while the ceramic case provides robust thermal and mechanical reliability. Rated for 0.05W (1/20) per resistor (0.4W total) and 100V maximum voltage, it operates over a -70°C to +125°C temperature range, making it suitable for harsh environments.

GS4B024121BT Features

• Precision Performance: ±0.1% tolerance and ±50ppm/°C TCR for critical analog/digital circuits.
• Robust Construction: Ceramic substrate and gull-wing termination ensure durability in surface-mount applications.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm SOIC footprint with 1.27mm terminal pitch.
• High Reliability: Thin-film technology delivers long-term stability under 125°C maximum operating temperature.
• Bussed Design: Simplified PCB layout with shared bus connections, reducing component count.

GS4B024121BT Applications

Ideal for precision voltage division, signal conditioning, and impedance matching in:

• Industrial Control Systems: PLCs, sensor interfaces, and instrumentation requiring drift-free resistance.
• Medical Electronics: Patient monitoring and diagnostic equipment where accuracy is critical.
• Automotive (Non-Automotive Rated): Test/measurement modules or prototyping (note: not PPAP/automotive-qualified).
• Aerospace & Defense: Avionics and communication systems needing stable performance over wide temperature ranges.

Conclusion of GS4B024121BT

The GS4B024121BT excels in applications demanding high precision, compactness, and thermal resilience. Its ceramic thin-film construction and bussed architecture offer superior performance over standard thick-film networks, particularly in environments with fluctuating temperatures or stringent accuracy requirements. While not automotive-compliant, it remains a cost-effective solution for industrial, medical, and aerospace designs where reliability and tolerance are paramount.
