GS4B021690DCT

GS4B021690DCT Description

The GS4B021690DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 169Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it combines 0.4W total power dissipation (0.05W per resistor) with a compact footprint (4.9mm × 5.99mm × 1.45mm). Its 100V maximum voltage rating and thick-film technology make it suitable for precision analog and digital circuits.

GS4B021690DCT Features

• Precision Performance: 0.5% tolerance and ±50ppm/°C TCR for stable operation in temperature-variable environments.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Space-Efficient: 8-pin SOIC (1.27mm pitch) optimizes PCB real estate while supporting surface-mount assembly.
• High Power Handling: 0.4W total power rating (derated up to 125°C) outperforms similar networks in its class.
• Automation-Friendly: Gull-wing leads enable reliable soldering for high-volume manufacturing.
• Non-Automotive: Ideal for industrial and telecom applications where PPAP compliance is not required.

GS4B021690DCT Applications

This resistor network excels in:

• Voltage Division/Current Sensing: Precision dividers in ADC/DAC circuits.
• Impedance Matching: High-frequency signal conditioning in RF/communication systems.
• Medical/Test Equipment: Stable reference networks for sensitive instrumentation.
• Industrial Controls: Feedback loops in power supplies or motor drives.
• Consumer Electronics: Dense PCBs requiring matched resistance values (e.g., audio amplifiers).

Conclusion of GS4B021690DCT

The GS4B021690DCT stands out for its precision, power efficiency, and compact design, making it a superior choice over generic thick-film arrays. While not RoHS-compliant, its ceramic construction and thin-film technology ensure reliability in non-automotive precision applications. Engineers will value its balanced trade-off between performance and cost in medium-power analog systems. For designs requiring tight tolerances and thermal stability, this network delivers consistent results under rigorous operating conditions.
