GS4A024121JT

GS4A024121JT Description

The GS4A024121JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 4.12KΩ resistance and a ±5% tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient, ensuring minimal resistance drift under varying environmental conditions. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for moderate-power circuits. The SOIC-C series construction provides excellent mechanical durability, with a compact 4.9mm x 5.99mm x 1.45mm footprint and gull-wing termination for reliable surface-mount assembly.

GS4A024121JT Features

• Isolated Resistor Network: Four independent resistors in an 8-pin SOIC package, ideal for signal isolation.
• High Stability: ±50ppm/°C TCR and 5% tolerance ensure consistent performance in precision circuits.
• Robust Construction: Ceramic case and thin-film technology enhance thermal and mechanical reliability.
• Surface-Mount Design: Gull-wing terminals and 1.27mm pitch simplify PCB assembly.
• Wide Operating Range: Functions reliably from -70°C to +125°C, with derated power up to 125°C.
• Compact Dimensions: 4.9mm length, 5.99mm depth, and 1.45mm height save board space.

GS4A024121JT Applications

This resistor network excels in applications demanding precision, stability, and compactness, such as:

• Analog Signal Conditioning: Voltage dividers, feedback networks, and sensor interfaces.
• Industrial Control Systems: Isolated measurement circuits and PLCs.
• Medical Electronics: Patient monitoring equipment requiring low drift.
• Automotive Electronics (non-AECQ): Non-safety-critical systems like infotainment or lighting.
• Test & Measurement Equipment: Calibration circuits and reference networks.

Conclusion of GS4A024121JT

The GS4A024121JT combines high precision, thermal stability, and compact packaging, making it a versatile choice for engineers designing reliable analog circuits. Its isolated resistors, low TCR, and robust ceramic construction distinguish it from generic arrays, particularly in industrial and medical applications where performance consistency is critical. While not PPAP or automotive-qualified, it remains a cost-effective solution for non-safety-critical systems requiring tight tolerance and durability.
