GS4B028251DBT Description

The GS4B028251DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers an 8.25KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it combines 0.4W total power dissipation (0.05W per resistor) with a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The RoHS-non-compliant device is supplied in tube packaging, ensuring safe handling and storage.

GS4B028251DBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive signal conditioning.
• Compact & Robust: 4.9mm × 5.99mm × 1.45mm ceramic SOIC package with ±0.1mm length/height tolerances for reliable PCB integration.
• High Power Density: 0.4W total rating (0.05W per resistor) at derated power up to 125°C.
• BUS Configuration: Simplifies circuit design in multi-channel systems (e.g., voltage dividers, pull-up networks).
• Automotive-Grade Alternatives Available: While this model is not PPAP/AEC-Q200 qualified, TT Electronics offers variants for harsh environments.

GS4B028251DBT Applications

• Industrial Control Systems: Precision current sensing, ADC reference networks.
• Test & Measurement Equipment: Calibration circuits, signal attenuation.
• Medical Electronics: Patient monitoring, diagnostic instrumentation.
• Telecom Infrastructure: Line termination, impedance matching.
• Power Management: Feedback loops in DC-DC converters.

Conclusion of GS4B028251DBT

The GS4B028251DBT excels in high-accuracy, space-constrained designs requiring stable resistance over temperature. Its ceramic construction and thin-film technology outperform carbon/composite networks in long-term drift and thermal performance. While not automotive-qualified, it is ideal for industrial, medical, and telecom applications where precision and reliability are critical. Engineers should evaluate derating requirements for >70°C operation and consider RoHS alternatives if compliance is mandatory.
