GS4A0128R0JFT Description

The GS4A0128R0JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 4-resistor isolated network features a 28Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched circuits. Encased in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology and ±100ppm/°C temperature coefficient provide excellent stability across its operating range of -70°C to +125°C, while the 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for low-power, high-voltage environments.

GS4A0128R0JFT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High-Temperature Stability: Ceramic substrate and thin-film construction ensure minimal drift at elevated temperatures (up to 125°C).
• Precision Tolerance: ±5% absolute tolerance and ±1% ratio tolerance for matched applications.
• Robust Packaging: SOIC-C series with a rectangular ceramic case enhances thermal dissipation and mechanical durability.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive (non-AECQ) applications.
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads simplify PCB integration.

GS4A0128R0JFT Applications

This resistor network excels in:

• Precision voltage dividers and sensor signal conditioning due to its tight ratio tolerance.
• Isolated feedback circuits in power supplies and motor drives, leveraging its high-voltage capability.
• Industrial control systems requiring stable performance across wide temperature ranges.
• Test and measurement equipment where low thermal drift (±100ppm/°C) is critical.
• Non-automotive embedded systems (PPAP non-compliant) needing compact, high-reliability networks.

Conclusion of GS4A0128R0JFT

The GS4A0128R0JFT stands out for its ceramic-based isolation, precision tolerances, and broad thermal operating range, making it a superior choice for demanding electronics.
