GS4A028250JGT Description

The GS4A028250JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC (Small Outline Integrated Circuit) package features four isolated thin-film resistors, each rated at 825Ω ±5% tolerance, with a ±50ppm/°C temperature coefficient for minimal resistance drift. The SOIC-C series construction ensures robust performance in harsh environments, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. Its 0.1W (1/10W) power rating per resistor and 0.4W total power dissipation make it suitable for low-power circuits, while the 100V maximum voltage rating accommodates moderate voltage applications.

GS4A028250JGT Features

• Ceramic Case & Thin-Film Technology: Ensures high reliability, low noise, and excellent thermal stability.
• Isolated Resistors (4x 825Ω): Independent elements reduce crosstalk, ideal for signal isolation.
• Tight Tolerance: ±5% absolute tolerance and ±2% ratio tolerance for precision matching.
• Wide Temperature Range: Operates from -55°C to +125°C (derated above 70°C).
• Gull Wing Termination: Facilitates surface-mount (SMD) assembly with a 1.27mm terminal pitch.
• Compact Dimensions: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• Non-Automotive, Non-PPAP: Suitable for industrial and commercial applications.

GS4A028250JGT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Isolation Circuits: Buffering and impedance matching in communication systems.
• Sensor Interfaces: Stable reference resistors for RTDs or bridge circuits.
• Medical & Test Equipment: Low-drift resistance networks for calibration modules.
• Power Management: Current-limiting or pull-up/down networks in DC/DC converters.

Conclusion of GS4A028250JGT

The GS4A028250JGT combines ceramic durability, thin-film precision, and isolated design to deliver consistent performance in demanding electronic systems. Its low TCR (±50ppm/°C), compact SOIC footprint, and 5% tolerance make it a versatile choice for engineers prioritizing stability and space efficiency. While not PPAP or automotive-qualified, it is ideal for industrial, medical, and instrumentation applications where reliability and thermal resilience are critical. For designs requiring matched resistors with minimal drift, this network offers a cost-effective, high-performance solution.
