GS4B033921DCT Description

The GS4B033921DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a BUS configuration, each with a 3.92KΩ resistance and a tight 0.5% tolerance, ensuring reliable performance in precision circuits. Encased in a ceramic SOIC package, this 8-pin Gull Wing SMD component offers excellent thermal stability with a ±25ppm/°C temperature coefficient and operates within a wide temperature range of 70°C to 125°C. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it is engineered for stability in compact, high-density PCB designs.

GS4B033921DCT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• High-Density SOIC-8 Format: Saves board space while providing 7 isolated resistors in a single package.
• Wide Operating Range: Rated for -55°C to +125°C (derated power up to 125°C), suitable for industrial and automotive prototypes (though not PPAP/automotive-qualified).
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 1.27mm pitch for compatibility with automated assembly.
• Non-RoHS Compliance: Ideal for legacy systems or applications exempt from RoHS restrictions.

GS4B033921DCT Applications
