GS4B0128R0GFT Description

The GS4B0128R0GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications. This ceramic-based thin-film resistor array offers a 28Ω resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in demanding circuits. Its ±100ppm/°C temperature coefficient provides stability across a wide operating range of -55°C to +125°C, derated up to 70°C to 125°C. The SOIC-C series construction features a compact 4.9mm × 5.99mm footprint with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation (0.05W per resistor), it balances power handling with miniaturization.

GS4B0128R0GFT Features

• Bussed Network Design: Simplifies PCB layout by connecting resistors in a shared-bus configuration, reducing component count.
• High Stability: Thin-film technology and ceramic substrate ensure low noise and excellent thermal performance.
• Precision Tolerances: ±2% absolute and ±1% ratio tolerance for matched resistance values in differential circuits.
• Robust Construction: SOIC package with 1.27mm terminal pitch and 1.45mm profile suits high-density designs.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive (non-AEC-Q200) applications.
• Non-RoHS (Not Compliant): Suitable for legacy or niche systems requiring traditional materials.

GS4B0128R0GFT Applications

• Voltage Divider Networks: Precision dividers in sensor interfaces or ADC circuits.
• Bus Termination: Signal integrity in CAN, LIN, or I2C buses due to matched impedance.
• Industrial Controls: PLCs, motor drives, and power supplies benefiting from stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits requiring tight tolerance and low drift.
• Legacy Electronics: Non-RoHS compliant systems where material restrictions are not critical.

Conclusion of GS4B0128R0GFT

The GS4B0128R0GFT excels in space-constrained, precision applications with its bussed thin-film network, offering superior thermal stability and tolerance accuracy. While not automotive-grade (PPAP No), its 100V rating and ceramic durability make it a robust choice for industrial and instrumentation designs. Engineers will value its simplified routing and consistent performance, though RoHS compliance must be verified for regulated markets. Ideal for high-reliability systems where resistor matching and compactness are paramount.
