GS4B033240DT Description

The GS4B033240DT 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 324Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°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.

GS4B033240DT Features

• High Precision: ±0.5% absolute tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Ceramic substrate with thin-film technology ensures durability and long-term reliability.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm SOIC package with gull-wing terminals for easy PCB integration.
• Bussed Configuration: Simplifies circuit design by connecting multiple resistors to a common node (BUS).
• Wide Operating Range: Derated power operation up to 125°C, ideal for industrial and automotive-grade applications (though not PPAP-certified).
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring non-compliant materials.

GS4B033240DT Applications
