GS4B021242CAT Description

The GS4B021242CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 12.4KΩ resistance per element with an ultra-tight ±0.25% absolute tolerance and ±0.05% ratio tolerance, this ceramic-based thin-film network ensures exceptional stability and accuracy. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments requiring thermal resilience. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable PCB mounting. Rated at 100V maximum voltage and 0.4W total power dissipation, it balances performance with space efficiency.

GS4B021242CAT Features

• Precision Engineering: Thin-film technology delivers ±0.25% tolerance and low TCR (±50ppm/°C) for critical analog/digital circuits.
• Robust Construction: Ceramic substrate enhances thermal conductivity and durability under 70–125°C derated power conditions.
• Space-Saving Design: Narrow SOIC (8-pin) package with 1.27mm pitch optimizes board real estate.
• Bussed Topology: 7 resistors share a common bus, simplifying circuit design in voltage-divider or pull-up networks.
• High Voltage Handling: 100V rating supports industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Stable Power Dissipation: 0.05W per resistor (0.4W total) ensures reliability in continuous operation.

GS4B021242CAT Applications
