GS4A032702FAT

GS4A032702FAT Description

The GS4A032702FAT from TT Electronics/IRC is a high-precision 27KΩ, 4-resistor network in an 8-pin narrow SOIC package, designed for demanding isolation and signal conditioning applications. Built with thin-film technology on a ceramic substrate, it offers superior stability (±25ppm/°C) and tight ±1% absolute tolerance (±0.05% ratio tolerance), ensuring reliable performance in precision circuits. The isolated (ISOL) circuit design allows independent resistor operation, while the SOIC-C series construction provides robust thermal and mechanical resilience. Rated for 0.1W per resistor (0.4W total), it operates from 70°C to 125°C with a 100V maximum voltage rating, making it suitable for high-reliability environments.

GS4A032702FAT Features

• Ceramic Case & Thin Film: Enhances thermal conductivity and long-term stability.
• Isolated Resistors (4x): Independent 27KΩ elements for flexible circuit design.
• Tight Tolerances: ±1% absolute, ±0.05% ratio tolerance for precision matching.
• Low TCR (±25ppm/°C): Minimal resistance drift across temperature.
• SOIC-8 Package: Compact (4.9mm x 5.99mm x 1.45mm) with gull-wing leads for surface mounting.
• High Voltage Rating (100V): Suitable for industrial and automotive-grade isolation barriers.
• Wide Temp Range: Operates up to 125°C with derated power at elevated temperatures.

GS4A032702FAT Applications

• Isolation Circuits: Signal conditioning in PLCs, industrial sensors, and medical devices.
• Precision Voltage Dividers: ADC/DAC reference networks, instrumentation amplifiers.
• Automotive Electronics: Engine control units (ECUs) where temperature stability is critical (note: non-automotive qualified).
• Test & Measurement Equipment: Calibration circuits requiring matched resistors.
• Power Supplies: Feedback networks in isolated DC/DC converters.

Conclusion of GS4A032702FAT

The GS4A032702FAT excels in applications demanding high precision, thermal stability, and electrical isolation. Its ceramic thin-film construction, low TCR, and tight tolerances make it ideal for critical analog designs, though it lacks PPAP/automotive certification. Engineers will value its SOIC footprint compatibility and robust performance in harsh environments, bridging the gap between cost-effective networks and ultra-high-end discrete solutions.
