GS4A039092GFT Description

The GS4A039092GFT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a resistance value of 90.9 kΩ and a tight ±2% absolute tolerance (±1% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±25 ppm/°C, ensuring stability in varying thermal conditions. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning applications. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A039092GFT Features

• Ceramic SOIC package for enhanced thermal and mechanical reliability.
• Isolated resistor elements minimize crosstalk in high-impedance circuits.
• Thin-film technology delivers superior accuracy (±2%) and low TCR (±25 ppm/°C).
• Compact dimensions (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• 1.27mm terminal pitch for compatibility with standard SOIC layouts.
• Non-automotive (PPAP No) and EU RoHS non-compliant, restricting use in certain regulated environments.

GS4A039092GFT Applications

Ideal for precision circuitry requiring stable resistance ratios, such as:

• Isolation amplifiers and medical instrumentation (e.g., patient monitoring).
• Industrial control systems where thermal drift must be minimized.
• Test & measurement equipment demanding high accuracy (e.g., bridge networks).
• Telecom infrastructure for signal conditioning and impedance matching.
• Aerospace and defense electronics leveraging its ceramic ruggedness.

Conclusion of GS4A039092GFT

The GS4A039092GFT excels in applications requiring high isolation, tight tolerance, and thermal stability. Its ceramic construction and thin-film resistors offer long-term reliability, while the SOIC footprint ensures design flexibility. Though unsuitable for automotive or RoHS-regulated markets, it remains a top choice for precision analog designs where performance outweighs compliance needs. Engineers should verify its unconfirmed status with TT Electronics/IRC for critical deployments.
