GS4B022942FT

GS4B022942FT Description

The GS4B022942FT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a ceramic SOIC package, this thin-film resistor network offers a 29.4KΩ resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 8-pin narrow SOIC (SOIC-C) form factor (4.9mm × 5.99mm × 1.45mm) and gull-wing termination make it ideal for surface-mount assembly in space-constrained designs. With a derated power handling of 0.05W per resistor (0.4W total) and a 100V maximum voltage rating, it balances compactness with robust performance.

GS4B022942FT Features

• Ceramic substrate for enhanced thermal and mechanical reliability.
• Bussed (BUS) circuit design simplifies routing in voltage-divider or pull-up/down networks.
• Thin-film technology delivers superior accuracy (±1%) and low TCR (±50ppm/°C).
• Narrow SOIC (SOIC-C) package optimizes PCB space while supporting automated placement.
• Wide temperature range (-70°C to +125°C) suits industrial and automotive-adjacent applications.
• Non-compliant with EU RoHS, making it suitable for legacy or exempted systems.

GS4B022942FT Applications

This resistor network excels in:

• Analog signal conditioning (e.g., sensor interfaces, ADC/DAC circuits).
• Voltage division in power management or feedback loops.
• Pull-up/down networks for digital buses (I2C, SPI) requiring stable bias.
• Industrial control systems where temperature fluctuations demand stable performance.
• Legacy electronics or niche applications exempt from RoHS restrictions.

Conclusion of GS4B022942FT

The GS4B022942FT stands out for its ceramic construction, precision thin-film resistors, and compact SOIC-C footprint, offering engineers a reliable solution for high-stability circuits. While not PPAP-capable or automotive-grade, its wide temperature range and bussed design make it versatile for industrial, instrumentation, and prototyping use. Its non-RoHS status may limit modern applications but remains valuable for specialized or exempted designs. For designs prioritizing accuracy, thermal resilience, and space efficiency, this network is a compelling choice.
