GS8B034871DCT

GS8B034871DCT Description

The GS8B034871DCT 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) configuration device integrates 15 thin-film resistors, each with a 4.87KΩ resistance and an absolute tolerance of ±0.5%. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount (SMD) assembly. With a 0.8W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness with reliability.

GS8B034871DCT Features

• Precision Engineering: Thin-film technology delivers ±0.5% tolerance and ±0.25% ratio tolerance, critical for analog signal conditioning.
• Robust Construction: Ceramic substrate enhances thermal stability and durability, outperforming polymer-based networks.
• Space-Efficient Design: 9.91mm × 5.99mm footprint and 1.45mm profile suit high-density PCB layouts.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C, ideal for industrial/automotive underhood applications (though not PPAP-certified).
• Low TCR: ±25ppm/°C minimizes resistance drift, ensuring accuracy in precision circuits like ADCs or voltage dividers.

GS8B034871DCT Applications

This resistor network excels in:

• Signal Processing: Voltage division and impedance matching in data acquisition systems and sensor interfaces.
• Industrial Controls: PLC modules and power supply feedback loops requiring stable, low-drift resistance.
• Test & Measurement Equipment: Calibration circuits where ratio tolerance (±0.25%) is critical.
• Aerospace & Defense: Non-RoHS compliant variants may be used in legacy systems prioritizing performance over environmental restrictions.

Conclusion of GS8B034871DCT

The GS8B034871DCT stands out for its precision, thermal resilience, and compact form factor, making it a superior choice over generic resistor arrays in critical analog designs. While not automotive-grade or RoHS-compliant, its ceramic construction and tight tolerances cater to specialized industrial, aerospace, and high-reliability applications where performance outweighs regulatory constraints. Engineers will value its repeatability in bussed configurations and low TCR for mission-critical circuits.
