GS4A037682JBT Description

The GS4A037682JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 76.8KΩ and a ±5% absolute tolerance. The network boasts a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it is engineered for reliability in demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations ensures compatibility with standard surface-mount assembly processes.

GS4A037682JBT Features

• Isolated Circuit Design: Each resistor is electrically isolated, reducing crosstalk and improving signal integrity.
• High Precision: ±0.1% ratio tolerance ensures tight matching for differential signal applications.
• Robust Construction: Ceramic case provides excellent thermal stability and mechanical durability.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power above 70°C).
• Low TCR: ±25ppm/°C minimizes resistance drift with temperature fluctuations.
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads simplify PCB integration.

GS4A037682JBT Applications

This resistor network is ideal for:

• Precision analog circuits (e.g., instrumentation amplifiers, ADCs/DACs).
• Industrial control systems requiring stable voltage dividers or pull-up networks.
• Medical electronics where low drift and high isolation are critical.
• Automotive subsystems (non-safety-critical, given its non-automotive PPAP status).
• Telecommunications equipment leveraging its tight tolerance for impedance matching.

Conclusion of GS4A037682JBT
