GS4B023301GDT Description

The GS4B023301GDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Encased in a ceramic SOIC-C series housing, it offers a 3.3KΩ resistance per element with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in differential signal paths. The thin-film technology and ±50ppm/°C temperature coefficient provide excellent thermal stability, while the 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) suit moderate-power circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, with robust -70°C to +125°C derated operating range.

GS4B023301GDT Features

• Ceramic Construction: Enhances thermal management and durability in harsh environments.
• Bussed Network Topology: Simplifies PCB layout for common-voltage distribution (e.g., pull-up/pull-down networks).
• Precision Tolerance: ±2% absolute and ±0.5% ratio tolerance for matched resistance pairs, critical for analog signal conditioning.
• Low TCR (±50ppm/°C): Minimizes resistance drift across temperature fluctuations.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for high-density designs.
• Automation-Friendly: 1.27mm terminal pitch and gull-wing leads enable reliable pick-and-place mounting.

GS4B023301GDT Applications

• Voltage Divider Networks: Precision dividers in sensor interfaces or ADC reference circuits.
• Bus Termination: Impedance matching for I²C, SPI, or other low-voltage digital buses.
• Industrial Controls: Stable resistance in PLCs, motor drives, and power supplies where temperature variations occur.
• Medical Electronics: Reliable performance in patient monitoring equipment due to low drift.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems requiring ceramic robustness.

Conclusion of GS4B023301GDT

The GS4B023301GDT excels in applications demanding tight tolerance, thermal stability, and compact form factors. Its ceramic substrate and thin-film technology outperform standard epoxy-based networks in high-temperature or precision scenarios. While not PPAP or automotive-qualified, it is ideal for industrial, medical, and instrumentation designs where consistent resistance matching and low TCR are paramount. The SOIC package ensures compatibility with mainstream SMT processes, making it a versatile choice for engineers prioritizing reliability and space efficiency.
