GS4A012400GGT

GS4A012400GGT Description

The GS4A012400GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. This 4-resistor isolated network features a 240Ω resistance value with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in critical 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 reliable surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±100ppm/°C temperature coefficient and a 0.1W power rating per resistor (0.4W total). Rated for 125°C maximum operating temperature, it supports derated operation up to 70–125°C, making it suitable for thermally challenging designs.

GS4A012400GGT Features

• Isolated Circuit Design: Independent resistors (ISOL configuration) for flexible circuit integration.
• High Precision: ±2% tolerance on both absolute and ratio values, ideal for matched impedance applications.
• Robust Construction: Ceramic case ensures durability and thermal stability in harsh conditions.
• Wide Voltage Range: Supports up to 100V maximum voltage, suitable for industrial and automotive (non-Automotive PPAP) systems.
• Low TCR: ±100ppm/°C minimizes resistance drift across temperature fluctuations.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for easy PCB assembly.
• Non-RoHS Compliant: Suitable for legacy or specialized applications where RoHS exemptions apply.

GS4A012400GGT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers, feedback networks, and analog signal processing.
• Industrial Controls: Isolated measurement circuits, PLCs, and sensor interfaces.
• Test & Measurement Equipment: Calibration circuits and reference networks requiring stable resistance ratios.
• Power Management: Current-limiting and load-sharing in low-power DC/DC converters.
• Legacy Systems: Non-RoHS compliant designs or high-reliability military/aerospace applications (where permitted).
