GS7B032490GCT Description

The GS7B032490GCT from TT Electronics/IRC is a high-precision bussed resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC (SOIC-C) ceramic package, this device integrates 13 thin-film resistors with a 249Ω resistance value and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -55°C to +125°C, with derated power handling up to 125°C. The network offers a 0.7W total power rating (0.05W per resistor) and supports 100V maximum voltage, making it suitable for precision analog and digital circuits.

GS7B032490GCT Features

• Ceramic Construction: Enhances thermal stability and reliability in harsh environments.
• Bussed Design: Simplifies PCB layout by connecting multiple resistors to a common node (BUS).
• Low TCR (±25ppm/°C): Minimizes resistance drift over temperature variations.
• Thin-Film Technology: Delivers high accuracy and low noise for precision applications.
• Gull Wing Termination: Ensures robust surface-mount compatibility (SOIC package).
• Compact Dimensions: 8.66mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation use.

GS7B032490GCT Applications

This resistor network excels in:

• Voltage Divider Networks: Precision signal conditioning in ADCs/DACs.
• Bus Termination: Impedance matching in high-speed digital circuits (e.g., memory interfaces).
• Sensor Interface Circuits: Stable biasing for RTDs or strain gauges.
• Industrial Control Systems: Reliable performance in PLCs and motor drives.
• Test & Measurement Equipment: Low-drift resistance for calibration standards.

Conclusion of GS7B032490GCT

The GS7B032490GCT stands out for its ceramic-packaged durability, tight tolerance (±2%), and low TCR, making it a superior choice over plastic-encased networks in high-temperature or precision-critical designs. While not RoHS-compliant, its thin-film technology and bussed architecture streamline circuit integration, reducing component count and board space. Ideal for industrial, telecom, and precision analog systems, this network balances performance with cost efficiency for non-automotive applications.
