GS7B034530GT

GS7B034530GT Description

The GS7B034530GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors with a 453Ω resistance value and a tight ±2% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring reliability in demanding environments. Its ±25ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating and 0.7W total power dissipation make it suitable for robust circuit designs. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, offering mechanical stability and ease of assembly.

GS7B034530GT Features

• Precision Thin-Film Technology: Delivers stable performance with ±25ppm/°C TCR and ±2% absolute tolerance.
• Robust Ceramic Package: Enhances thermal management and durability in harsh conditions.
• Bussed Network Design: Simplifies PCB layout with a common bus connection for all 13 resistors.
• High Power Handling: 0.05W per resistor (0.7W total) ensures reliability in power-sensitive applications.
• Narrow SOIC (5.99mm × 8.66mm): Saves board space while maintaining 1.27mm terminal pitch for manufacturability.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C).
