GS8B033480DT

GS8B033480DT Description

The GS8B033480DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, this bussed (BUS) network integrates 15 thin-film resistors, each with a 348Ω resistance and an ultra-tight ±0.5% tolerance. The device operates over a wide temperature range (-70°C to +125°C) with a low ±25ppm/°C temperature coefficient, ensuring stability in fluctuating environments. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-reliability circuits. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly.

GS8B033480DT Features

• Precision Performance: ±0.5% absolute tolerance and ±25ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Space-Efficient: Compact 9.91mm × 5.99mm × 1.45mm footprint (SOIC-16) saves PCB real estate.
• Bussed Topology: Simplified circuit design with shared common terminals (BUS configuration).
• Wide Operating Range: Derated power up to 125°C, ideal for industrial/automotive underhood applications (though not PPAP/automotive-qualified).
• Thin-Film Technology: Delivers low noise and high stability vs. thick-film alternatives.

GS8B033480DT Applications

• Voltage Divider Networks: Precision attenuation in sensor interfaces or ADC front-ends.
• Pull-Up/Pull-Down Arrays: Signal integrity maintenance in digital buses (e.g., I²C, SPI).
• Medical/Test Equipment: High-accuracy instrumentation requiring stable resistance over temperature.
• Industrial Controls: PLCs, motor drives, and power management systems where ceramic reliability outperforms polymer-based networks.
• Aerospace & Defense: Non-RoHS version suits legacy systems needing hermetic-like performance.

Conclusion of GS8B033480DT

The GS8B033480DT excels in precision, thermal resilience, and miniaturization, distinguishing itself from generic resistor arrays with its ceramic thin-film architecture and bussed design. While not automotive-grade, its 125°C capability and ±0.5% tolerance make it a top choice for high-end industrial, medical, and aerospace designs where component-level accuracy directly impacts system performance. Engineers should evaluate its non-RoHS status for compliance but can leverage its TT Electronics/IRC pedigree for mission-critical analog circuits.
