GS4A011133GGT

GS4A011133GGT Description

The GS4A011133GGT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 113KΩ resistance value and ±2% absolute tolerance, this ceramic-based network ensures reliable signal conditioning and voltage division. Its ±100ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for environments operating at 70°C to 125°C. The SOIC-C series features gull-wing termination for robust surface-mount assembly, with a compact footprint (4.9mm × 5.99mm × 1.45mm) and tight tolerances (±0.1mm height/length, ±0.2mm depth). Non-compliant with EU RoHS, it targets industrial and legacy systems where ceramic durability and isolation are critical.

GS4A011133GGT Features

• Isolated Circuit Design: Independent resistors (ISOL) prevent crosstalk, ideal for multi-channel systems.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
• High Voltage Handling: Supports up to 100V, suitable for power supply dividers and sensor interfaces.
• Precision Tolerance: ±2% absolute and ratio tolerance ensures consistent performance in matched networks.
• Ceramic Package: Enhances thermal conductivity and mechanical strength for harsh environments.
• Narrow SOIC Form Factor: Saves PCB space while maintaining 1.27mm terminal pitch for easy soldering.

GS4A011133GGT Applications

• Industrial Control Systems: Signal conditioning in PLCs and motor drives.
• Test & Measurement Equipment: Precision voltage dividers and calibration circuits.
• Medical Devices: Isolated feedback networks in diagnostic instruments.
• Automotive Legacy Systems: Non-RoHS compliant variants for aftermarket or niche vehicular electronics.
• Power Management: Load sharing and bias networks in DC-DC converters.

Conclusion of GS4A011133GGT

The GS4A011133GGT excels in applications demanding high isolation, precision, and thermal resilience. Its ceramic construction and thin-film technology offer superior longevity and performance over polymer-based networks. While not suited for modern RoHS-mandated designs, it remains a robust choice for industrial, medical, and legacy automotive systems requiring reliable resistance networks with tight tolerances and low thermal drift. Engineers will value its balance of compactness, power handling, and electrical isolation in critical circuits.
