GS7B033480GT

GS7B033480GT Description

The GS7B033480GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed network integrates 13 thin-film resistors with a common bus configuration, each rated at 348Ω (±2% tolerance). The device operates within a wide temperature range of -70°C to +125°C, delivering 0.05W (1/20W) per resistor and a total power rating of 0.7W. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift, while the 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount PCB designs. The ceramic case enhances thermal stability, and the compact dimensions (8.66mm x 5.99mm x 1.45mm) optimize space efficiency.

GS7B033480GT Features

• Precision Thin-Film Technology: Delivers ±2% absolute tolerance and low TCR (±25ppm/°C) for stable performance.
• Robust Ceramic Package: Ensures high thermal conductivity and mechanical durability in harsh environments.
• Bussed Network Design: Simplifies circuit layout with 13 resistors sharing a common bus (BUS circuit designator).
• Surface-Mount SOIC Package: 14-pin narrow SOIC with 1.27mm terminal pitch for high-density PCB integration.
• Wide Operating Range: -70°C to +125°C with derated power up to 125°C, ideal for industrial and automotive (non-PPAP) applications.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.

GS7B033480GT Applications
