GS4A025492JAT Description

The GS4A025492JAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 54.9 kΩ and a ±5% absolute tolerance. The network operates within a temperature range of 70°C to 125°C, with a ±50 ppm/°C temperature coefficient, ensuring stability under varying thermal conditions. Encased in a rectangular ceramic SOIC package, it offers a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design make it ideal for automated assembly processes.

GS4A025492JAT Features

• Isolated Circuit Design: Each resistor is electrically isolated, reducing crosstalk and improving signal integrity.
• High Precision: ±5% absolute tolerance and ±0.05% ratio tolerance for applications requiring tight resistance matching.
• Robust Construction: Ceramic case ensures durability and thermal stability, even at 125°C maximum operating temperature.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height, ±0.2mm depth).
• Thin-Film Technology: Delivers low noise and high reliability compared to thick-film alternatives.
• Automation-Friendly: 1.27mm terminal pitch and SOIC package optimize pick-and-place efficiency.

GS4A025492JAT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning where ratio tolerance (±0.05%) is critical.
• Industrial Electronics: PLCs, motor drives, and power supplies requiring high-voltage (100V) isolation.
• Test & Measurement Equipment: Calibration circuits and signal attenuation with low TCR (±50 ppm/°C).
• Medical Devices: Patient monitoring systems demanding stable, noise-free resistance paths.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical functions in infotainment or control modules.

Conclusion of GS4A025492JAT

The GS4A025492JAT stands out for its isolated thin-film resistors, ceramic robustness, and precision tolerances, making it a superior choice for high-reliability electronics. While not PPAP or automotive-qualified, its thermal stability, compact form factor, and low TCR cater to demanding industrial, medical, and instrumentation applications. Engineers will appreciate its balance of performance and manufacturability, particularly in designs requiring matched resistance networks with minimal drift.
