GS4A032871JT

GS4A032871JT Description

The GS4A032871JT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications requiring stable thin-film resistance. With a 2.87KΩ resistance per element (±5% tolerance) and a ±25ppm/°C temperature coefficient, this network ensures reliable performance across a 70°C to 125°C derated power range, peaking at 125°C maximum operating temperature. Its 0.1W (1/10W) power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for moderate-power circuits. The gull-wing termination and surface-mount design (4.9mm x 5.99mm x 1.45mm) facilitate compact PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4A032871JT Features

• Isolated Circuit Design (ISOL): Independent resistors eliminate crosstalk, ideal for signal isolation.
• Thin-Film Technology: Delivers low noise and high stability vs. thick-film alternatives.
• Precision Tolerance: ±5% absolute tolerance and ±25ppm/°C TCR ensure consistent performance.
• Robust Construction: Ceramic substrate resists thermal stress and environmental degradation.
• Compact SOIC Package: 8-pin narrow profile (1.27mm pitch) saves board space.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power.

GS4A032871JT Applications

• Analog Signal Conditioning: Voltage dividers, feedback networks in op-amp circuits.
• Industrial Controls: PLCs, sensor interfaces requiring isolated impedance matching.
• Medical Electronics: Patient monitoring equipment where precision and reliability are critical.
• Automotive Systems (non-Automotive PPAP): Infotainment or lighting controls (note: not PPAP-qualified).
• Test & Measurement: Calibration circuits demanding low TCR drift.

Conclusion of GS4A032871JT

The GS4A032871JT excels in applications needing high isolation, precision, and compactness, leveraging ceramic thin-film construction for superior stability. While not RoHS-compliant or automotive-grade, its low TCR, isolated design, and robust package make it a standout choice for industrial, medical, and instrumentation designs. Engineers should verify "Unconfirmed" part status for critical projects but can rely on its TT Electronics/IRC pedigree for quality.
