GS4B033001DDT

GS4B033001DDT Description

The GS4B033001DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 3K Ohm configuration with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic SOIC-8 package, this surface-mount device (SMD) offers a 0.4W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB integration, while the rectangular ceramic case provides durability and thermal stability.

GS4B033001DDT Features

• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR for accuracy in critical circuits.
• Robust Construction: Ceramic substrate enhances thermal management and longevity.
• Compact Design: 4.9mm × 5.99mm × 1.45mm footprint optimizes space in dense layouts.
• High Reliability: 125°C maximum operating temperature suits harsh environments.
• Ease of Integration: Gull-wing leads and 1.27mm pitch simplify automated assembly.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP or automotive-grade.

GS4B033001DDT Applications

Ideal for precision analog and digital systems, including:

• Signal conditioning circuits (e.g., sensor interfaces, ADCs/DACs).
• Voltage dividers in measurement equipment.
• Bus termination networks (designator: BUS) for impedance matching.
• Industrial control systems requiring stable resistance under thermal stress.
• Medical devices where low drift and reliability are critical.

Conclusion of GS4B033001DDT

The GS4B033001DDT excels in applications demanding high precision, thermal stability, and compactness. Its thin-film technology and ceramic package outperform similar epoxy-based networks in thermal performance and longevity.
