GS4B018251DBT Description

The GS4B018251DBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers an 8.25KΩ resistance per resistor with a tight ±0.5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this network is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal performance.

GS4B018251DBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength compared to polymer-based arrays.
• High-Density Design: Compact 4.9mm × 5.99mm × 1.45mm footprint saves board space in miniaturized designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, ideal for industrial environments.
• Automated Assembly-Friendly: Gull-wing leads and tube packaging streamline pick-and-place processes.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and instrumentation applications where automotive compliance isn’t required.

GS4B018251DBT Applications

• Voltage Division/Current Limiting: Precision resistor networks in DAC/ADC reference circuits.
