GS4B031151JBT Description

The GS4B031151JBT from TT Electronics/IRC is a high-performance 7-resistor thin-film network designed for precision applications. Encased in a ceramic SOIC-8 package, it offers a 1.15KΩ resistance per element with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network features gull-wing terminations for reliable PCB connections. Its compact dimensions (4.9mm × 5.99mm × 1.45mm) and ±0.1mm height tolerance make it ideal for space-constrained designs.

GS4B031151JBT Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Ceramic case: Enhances thermal performance and durability in harsh environments.
• BUS circuit design: Simplifies routing in bus termination, pull-up/pull-down, and voltage divider applications.
• Low TCR (±25ppm/°C): Minimizes resistance drift under temperature fluctuations.
• High power density: 0.4W total rating in a compact SOIC package, outperforming similar networks.
• Automotive-grade alternatives available (though this variant is non-automotive and PPAP non-compliant).

GS4B031151JBT Applications

This resistor network excels in:

• Signal conditioning in industrial control systems.
• Bus termination for CAN, I2C, or SPI interfaces.
• Precision voltage dividers in test/measurement equipment.
• Embedded systems requiring stable biasing or load matching.
• Aerospace and defense electronics where ceramic packaging ensures reliability.

Conclusion of GS4B031151JBT

The GS4B031151JBT combines thin-film precision, robust ceramic construction, and compact SMD packaging to address demanding circuit design needs.
