GS4A022872GBT

GS4A022872GBT Description

The GS4A022872GBT 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 28.7kΩ resistance and a tight ±2% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint with gull-wing terminations for reliable surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances precision and durability.

GS4A022872GBT Features

• Isolated Resistors: Four independent 28.7kΩ thin-film resistors with ±0.1% ratio tolerance for matched performance.
• High Stability: ±50ppm/°C TCR and 2% tolerance ensure consistent operation under thermal stress.
• Robust Construction: Ceramic substrate and SOIC package provide mechanical strength and thermal dissipation.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power at elevated temperatures.
• Surface-Mount Ready: Gull-wing leads (1.27mm pitch) simplify PCB integration.
• Non-Automotive Grade: Ideal for industrial and commercial applications where PPAP compliance is not required.

GS4A022872GBT Applications

This resistor network excels in precision analog circuits, voltage dividers, and sensor signal conditioning where matched resistance values are critical. Its low TCR and high isolation make it suitable for:

• Medical instrumentation (e.g., patient monitoring systems).
• Test and measurement equipment (e.g., multimeters, oscilloscopes).
• Industrial control systems requiring stable feedback networks.
• Communication devices (e.g., RF modules, baseband processing).
