GS4B0251R0JDT Description

The GS4B0251R0JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. This ceramic-based resistor network offers a 51Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±0.5%, ensuring consistent performance in matched-resistor circuits. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal variability. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures reliable surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances compact dimensions (4.9mm × 5.99mm × 1.45mm) with high power handling.

GS4B0251R0JDT Features

• Bussed Network Design: 7 resistors connected in a common bus configuration, simplifying PCB layout for shared-voltage applications.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±5% absolute, ±0.5% ratio).
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive (non-AEC-Q200) use.
• Compact SOIC Package: 8-pin narrow profile (1.63mm seated height) with 1.27mm terminal pitch, optimized for high-density boards.
• Ceramic Substrate: Enhances thermal management and durability compared to polymer-based networks.
• Non-RoHS Compliant: Suitable for legacy or niche applications where RoHS exemptions apply.
