GS4A034020DT Description

The GS4A034020DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 402Ω resistance and an exceptional ±0.5% tolerance. Built with a rectangular ceramic package, it offers superior thermal stability and reliability, operating within a temperature range of 70°C to 125°C (derated power) and a maximum operating temperature of 125°C. The SOIC-C series construction ensures robust performance in surface-mount (SMD) applications, with a gull-wing termination style for secure PCB attachment.

GS4A034020DT Features

• Precision Performance: ±25ppm/°C temperature coefficient ensures minimal resistance drift under thermal stress.
• High Power Handling: 0.1W per resistor (0.4W total) with a 100V maximum voltage rating, suitable for compact, power-sensitive designs.
• Sturdy Ceramic Package: SOIC case style with ±0.1mm length/height tolerances and ±0.2mm depth tolerance for consistent mechanical fit.
• Isolated Resistors: Four independent 402Ω resistors with 0.5% absolute tolerance, ideal for precision voltage division or current sensing.
• Industrial-Grade Reliability: Non-automotive (PPAP No) but suited for industrial, telecom, and instrumentation applications.
