GS4B022701FFT

GS4B022701FFT Description

The GS4B022701FFT 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 substrate, it offers superior thermal stability with a ±50ppm/°C temperature coefficient and a tight ±1% absolute tolerance. Rated for 0.05W (1/20) per resistor (0.4W total), it operates across a 70°C to 125°C derated power range, with a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch ensure reliable surface-mount assembly, while the SOIC package (4.9mm x 5.99mm x 1.45mm) suits space-constrained designs.

GS4B022701FFT Features

• Bussed Network: 7 resistors tied to a common bus, simplifying circuit routing.
• Thin-Film Technology: Delivers low noise and high stability (±1% ratio tolerance).
• Wide Temperature Range: Derated up to 125°C, ideal for harsh environments.
• Precision Tolerance: ±1% absolute and ratio tolerance for matched performance.
• Robust Construction: Ceramic case ensures durability and thermal dissipation.
• Surface-Mount Ready: Gull-wing leads and ±0.1mm height/length tolerances for automated PCB assembly.

GS4B022701FFT Applications

This resistor network excels in:

• Voltage Division Circuits: Precision dividers in sensor interfaces or ADCs.
• Bus Termination: Signal integrity in high-speed digital systems (e.g., memory modules).
• Industrial Controls: Stable resistance in PLCs or motor drivers under thermal stress.
• Automotive (Non-Automotive Rated): Auxiliary systems requiring tight tolerance (note: not PPAP/automotive certified).
• Test Equipment: Calibration circuits demanding low TCR and matched ratios.

Conclusion of GS4B022701FFT

The GS4B022701FFT stands out for its ceramic-based reliability, thin-film precision, and bussed topology, making it a cost-effective solution for designs needing multiple matched resistors. While not RoHS-compliant or automotive-grade, its ±50ppm/°C TCR and 1% tolerance suit industrial, telecom, and instrumentation applications where thermal drift and space efficiency are critical. Its SOIC package balances performance with manufacturability, offering a robust alternative to discrete resistors in dense layouts.
