GS4B028251BBT

GS4B028251BBT Description

The GS4B028251BBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for BUS circuit applications, offering an 8.25KΩ resistance value with an ultra-tight 0.1% tolerance. Encased in a ceramic SOIC-8 package, this surface-mount device delivers 0.4W total power dissipation (0.05W per resistor) and operates across a wide temperature range of 70°C to 125°C. Its ±50ppm/°C temperature coefficient ensures stability in thermally demanding environments, while the 100V maximum voltage rating and gull-wing termination facilitate reliable PCB integration. Packaged in a tube, it meets industrial-grade requirements but is not PPAP or automotive qualified.

GS4B028251BBT Features

• Precision Thin-Film Technology: Delivers 0.1% tolerance and ±50ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Ceramic Construction: Enhances thermal performance and durability vs. polymer-based networks.
• Space-Efficient SOIC-8 Package: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm pitch for high-density designs.
• High Power Handling: 0.4W total dissipation (derated up to 125°C) outperforms standard 0.25W networks.
• Non-Compliant to EU RoHS: Suitable for legacy or exempted applications requiring leaded soldering.

GS4B028251BBT Applications

• Voltage Divider Networks: Precision attenuation in sensor interfaces (e.g., industrial RTD/thermocouple circuits).
• BUS Line Termination: Impedance matching in communication protocols (I²C, SPI) with low drift.
• Medical Instrumentation: Stable feedback networks in diagnostic equipment where tolerance is critical.
• Aerospace & Defense: Reliable performance in avionics control systems under thermal stress.
• Test & Measurement: Calibration references requiring long-term stability (±50ppm/°C).

Conclusion of GS4B028251BBT

The GS4B028251BBT excels in high-accuracy, thermally stable applications, leveraging ceramic thin-film technology to outperform conventional resistor arrays in precision and power handling. While unsuitable for automotive use, its 8.25KΩ BUS configuration, tight tolerances, and industrial-grade robustness make it ideal for mission-critical electronics where signal integrity and reliability are paramount. Engineers should evaluate RoHS compliance for regulated markets but can rely on its TT Electronics/IRC pedigree for demanding analog designs.
