GS4B022871DCT

GS4B022871DCT Description

The GS4B022871DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 7-resistor BUS-configuration array offers a 2.87KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD terminations, it delivers 0.4W total power dissipation (0.05W per resistor) and supports 100V maximum voltage ratings. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and ±0.1mm length/height tolerances make it ideal for space-constrained PCB designs.

GS4B022871DCT Features

• Precision Thin Film Technology: Ensures low noise and high accuracy for sensitive analog/digital circuits.
• Robust Ceramic Construction: Enhances thermal performance and reliability in harsh environments.
• BUS Circuit Design: Simplifies PCB layout for bus termination, voltage division, or pull-up/down networks.
• Automotive-Grade Alternatives: While not PPAP-certified, its 125°C max operating temperature suits industrial and telecom applications.
• Stable Performance: Low TCR (±50ppm/°C) and derated power handling up to 125°C outperform generic thick-film arrays.

GS4B022871DCT Applications

• Signal Conditioning: Precision voltage dividers in ADC/DAC circuits.
• Bus Termination: Impedance matching for high-speed data lines (e.g., SPI, I2C).
• Industrial Controls: Stable feedback networks in power supplies or sensor interfaces.
• Medical Electronics: Reliable resistance matching in diagnostic equipment.
• Aerospace Systems: Ceramic package resists vibration and thermal cycling.

Conclusion of GS4B022871DCT

The GS4B022871DCT excels in precision and durability, combining thin-film accuracy with ceramic ruggedness. Its BUS configuration, tight tolerances, and wide temperature range make it superior to standard thick-film networks for critical designs. While not RoHS-compliant or automotive-qualified, it remains a top choice for industrial, medical, and high-reliability electronics where performance outweighs compliance needs. Packaged in tubes for SMD assembly, it balances cost-efficiency with technical excellence.
