GS4B034120FCT Description

The GS4B034120FCT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for demanding circuit applications. Encased in a ceramic SOIC-8 package, it offers a 412Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network features gull-wing terminations with a 1.27mm pitch for reliable PCB integration. Its ceramic substrate enhances thermal stability, while the rectangular SOIC package (4.9mm x 5.99mm x 1.45mm) ensures compactness. Non-automotive and non-RoHS compliant, it is supplied in tubes for ease of handling.

GS4B034120FCT Features

• Precision Thin Film Technology: Delivers ±25ppm/°C TCR and 1% tolerance for critical analog/digital circuits.
• Robust Ceramic Construction: Superior thermal management and durability in harsh environments.
• Space-Efficient SOIC-8 Package: Ideal for high-density PCB designs with 4.9mm length and 1.45mm profile.
• BUS Circuit Designator: Optimized for bus termination, voltage division, or pull-up/down applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• Gull-Wing Termination: Ensures secure soldering and mechanical stability in SMT processes.

GS4B034120FCT Applications

• Signal Conditioning: Precision resistor networks for ADC/DAC reference circuits.
• Bus Termination: Impedance matching in high-speed data lines (e.g., SPI, I²C).
• Industrial Electronics: Sensor interfaces, power supplies, and control systems requiring stable resistance.
• Test & Measurement Equipment: Calibration and signal attenuation where low TCR is critical.
• Aerospace & Defense: Non-RoHS compliant variants for specialized legacy systems.

Conclusion of GS4B034120FCT

The GS4B034120FCT excels in applications demanding high precision, thermal stability, and compactness. Its ceramic thin-film design and SOIC-8 footprint make it a superior choice over polymer-based networks in environments with fluctuating temperatures or stringent accuracy requirements. While unsuitable for automotive or RoHS-regulated projects, it is a cost-effective solution for industrial, aerospace, and instrumentation designs where reliability and performance outweigh compliance needs.
