GS4A025902FBT Description

The GS4A025902FBT 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 59 kΩ resistance value and a tight ±1% absolute tolerance. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic case enhances thermal and mechanical durability. Rated for 0.1 W per resistor (0.4 W total) and 100 V maximum voltage, it is ideal for high-reliability circuits requiring minimal drift and high accuracy.

GS4A025902FBT Features

• Isolated Resistors: Four independent 59 kΩ resistors with ±1% tolerance and ±0.1% ratio tolerance for precision matching.
• Stable Performance: ±50 ppm/°C TCR and 125°C maximum operating temperature ensure reliability in harsh environments.
• Robust Construction: Ceramic substrate and SOIC package provide excellent thermal dissipation and mechanical strength.
• Surface-Mount Ready: Gull-wing terminations (1.27 mm pitch) facilitate easy PCB assembly.
• High Voltage Rating: Supports up to 100 V, suitable for industrial and automotive-grade applications (though non-automotive PPAP).

GS4A025902FBT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance and low drift.
• Industrial Electronics: Power supplies, instrumentation, and control systems where thermal stability is critical.
• Telecommunications: Signal conditioning and impedance matching in high-frequency modules.
• Test & Measurement Equipment: Calibration circuits and reference networks due to its ±0.1% ratio tolerance.
