GS4A018200GGT

GS4A018200GGT Description

The GS4A018200GGT from TT Electronics/IRC is a high-reliability ceramic resistor network designed for precision applications requiring stable performance under demanding conditions. This 4-resistor isolated network features an 820Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for robust surface-mount assembly. The thin-film technology delivers excellent stability, with a ±100ppm/°C temperature coefficient and a 0.1W power rating per resistor (0.4W total). Rated for 125°C maximum operating temperature, it suits environments with derated power requirements up to 70–125°C.

GS4A018200GGT Features

• Isolated Circuit Design: Independent resistors minimize crosstalk, ideal for signal isolation.
• High Power Density: 0.4W total dissipation in a compact SOIC package outperforms similar networks.
• Precision Thin Film: Low TCR (±100ppm/°C) and tight tolerances ensure long-term accuracy.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• Automation-Friendly: 1.27mm terminal pitch and gull-wing leads enable high-speed PCB assembly.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.

GS4A018200GGT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Isolation Circuits: Buffering and impedance matching in communication modules (RS-485, CAN).
• Power Management: Current sensing and feedback networks in DC/DC converters.
• Medical Electronics: Patient monitoring systems requiring stable, noise-resistant resistors.
• Test & Measurement: Calibration circuits where ratio tolerance (±2%) is critical.

Conclusion of GS4A018200GGT

The GS4A018200GGT stands out for its combination of precision, power handling, and isolation in a space-saving SOIC package. Its ceramic thin-film construction ensures reliability in harsh environments, while the 2% tolerance and low TCR make it a preferred choice for high-accuracy designs. Though not PPAP or automotive-qualified, it excels in industrial, medical, and instrumentation applications where consistent performance is paramount. Engineers will appreciate its balance of density, thermal resilience, and electrical stability compared to bulkier or less precise alternatives.
