GS4A021873GT

GS4A021873GT Description

The GS4A021873GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 187kΩ resistance and a tight ±2% tolerance. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating temperatures. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers reliable surface-mount compatibility, while the ceramic case enhances durability and heat dissipation. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), it balances compactness with robust electrical performance.

GS4A021873GT Features

• Isolated Resistors: Four independent 187kΩ resistors for flexible circuit design.
• High Stability: ±50ppm/°C TCR and ±2% tolerance ensure precision in critical applications.
• Robust Construction: Ceramic SOIC package with gull-wing leads for mechanical and thermal resilience.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power handling.
• Surface-Mount Ready: 1.27mm terminal pitch and compact dimensions (4.9mm x 5.99mm) suit high-density PCBs.
• Non-Automotive: Ideal for industrial and commercial electronics where PPAP compliance is not required.

GS4A021873GT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces.
• Analog Circuits: Feedback networks in op-amp configurations.
• Test & Measurement Equipment: Stable reference resistors for calibration.
• Power Supplies: Bias networks requiring low drift.
• Industrial Controls: Isolated resistor networks in PLCs and motor drives.

Conclusion of GS4A021873GT

The GS4A021873GT excels in applications demanding tight tolerance, low TCR, and rugged packaging. Its ceramic SOIC design and isolated resistors provide superior reliability compared to epoxy-based networks, particularly in high-temperature or vibration-prone environments. While not RoHS-compliant, it remains a cost-effective choice for non-automotive industrial systems where precision and durability outweigh regulatory constraints. Engineers will value its balance of performance, compactness, and thermal resilience in critical analog designs.
