GS4B032802JAT Description

The GS4B032802JAT 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 28KΩ resistance per element with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor), it supports 100V maximum voltage and features gull-wing terminations for reliable surface-mount (SMD) assembly. Its compact dimensions (4.9mm × 5.99mm × 1.45mm) and tight tolerances (±0.1mm height/length, ±0.2mm depth) make it ideal for space-constrained PCBs.

GS4B032802JAT Features

• Thin-film technology: Delivers superior accuracy and stability vs. thick-film alternatives.
• Ceramic substrate: Enhances thermal management and durability in harsh environments.
• BUS circuit design: Simplifies routing in multi-resistor applications like voltage dividers or pull-up networks.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress.
• Gull-wing terminals: Facilitates automated soldering and inspection.
• Non-automotive (PPAP No): Optimized for industrial/consumer electronics.

GS4B032802JAT Applications

This resistor network excels in:

• Signal conditioning circuits (ADC/DAC interfaces, sensor calibration).
• Bus termination/pull-up arrays in digital systems (I²C, SPI).
• Power supply feedback networks requiring tight tolerance.
• Medical/telecom equipment where long-term reliability is critical.
• High-density PCBs due to its SOIC footprint and low-profile (1.63mm seated height).

Conclusion of GS4B032802JAT

The GS4B032802JAT combines precision, power efficiency, and rugged packaging, making it a standout choice for engineers needing stable resistor networks in compact designs. While not RoHS-compliant, its ceramic construction and thin-film technology offer performance advantages over standard arrays, particularly in thermal and electrical stability. Ideal for industrial controls, test equipment, and communication hardware, this component balances cost and performance for mid-to-high-tier applications.
