GS4A0227R0JT

GS4A0227R0JT Description

The GS4A0227R0JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance characteristics. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 27Ω resistance and a ±5% tolerance. The device operates within a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient minimizes resistance drift, making it suitable for precision circuits. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), it balances power handling with space efficiency.

GS4A0227R0JT Features

• Isolated Resistor Design: Four independent 27Ω resistors with 5% tolerance, ideal for signal isolation or divider networks.
• Stable Thin-Film Technology: Delivers low TCR (±50ppm/°C) for consistent performance across temperature fluctuations.
• Robust Ceramic Package: SOIC-C series ensures mechanical durability and thermal stability in harsh conditions.
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Precision Dimensions: Tight tolerances on package height (±0.1mm) and depth (±0.2mm) facilitate automated PCB assembly.
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring non-compliant materials.

GS4A0227R0JT Applications

• Signal Conditioning: Isolated resistor networks in ADC/DAC circuits, voltage dividers, or sensor interfaces.
• Industrial Controls: PLC modules, motor drives, and power supplies where temperature stability is critical.
• Test & Measurement Equipment: Precision instrumentation requiring low-drift resistance values.
• Legacy Electronics: Systems exempt from RoHS compliance, such as military or aerospace subsystems.
• High-Density PCBs: Space-constrained designs leveraging the SOIC package’s compact profile.
