GS4B021182FFT

GS4B021182FFT Description

The GS4B021182FFT 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 technology. With a 11.8KΩ resistance per element, this ceramic-based network offers ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in critical circuits. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures reliable surface-mount compatibility. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances compactness (4.9mm × 5.99mm × 1.45mm) with durability.

GS4B021182FFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Bussed Network Design: Simplifies PCB layout by reducing discrete component count.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial/automotive underhood applications (though not PPAP/automotive-certified).
• Ceramic Substrate: Enhances thermal management and reliability vs. polymer-based networks.
• 1.27mm Terminal Pitch: Compatible with standard SOIC assembly processes.
• Non-RoHS (Not Compliant): Suitable for legacy or exempted systems requiring leaded components.

GS4B021182FFT Applications

• Voltage Divider Networks: Precision signal conditioning in sensor interfaces.
• Bus Termination: Impedance matching in high-speed digital systems (e.g., SPI, I²C).
• Industrial Control Systems: PLCs, motor drives, and power supplies where temperature stability is critical.
• Test & Measurement Equipment: Calibration circuits due to tight tolerance (±1%) and low TCR.
• Legacy Electronics Repair: Non-RoHS compliance aligns with older product designs.

Conclusion of GS4B021182FFT

The GS4B021182FFT excels in space-constrained, precision applications demanding thermal resilience and electrical consistency. Its ceramic SOIC package and bussed architecture reduce assembly complexity, while thin-film technology ensures long-term reliability. Though not automotive-grade, it is a cost-effective solution for industrial, communications, and instrumentation designs requiring stable resistance networks with minimal drift. Engineers should verify compatibility for RoHS-restricted projects.
