GS4B021372BT Description

The GS4B021372BT 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. This ceramic-based thin-film resistor network offers a 13.7KΩ resistance per element with an ultra-tight ±0.1% absolute tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The SOIC-C series construction provides robust performance with a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits.

GS4B021372BT Features

• High Precision: ±0.1% tolerance and ±50ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic substrate with thin-film technology ensures reliability in harsh environments.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing termination for easy PCB integration.
• Bussed Configuration: Simplifies circuit design by connecting resistors in a common bus topology.
• Wide Temperature Range: Derated power operation up to 125°C, ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Stable Performance: Low parasitic effects and excellent thermal management due to SOIC package design.
