GS4B012490GGT

GS4B012490GGT Description

The GS4B012490GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications requiring stable thin-film resistance. With a 249Ω resistance value (±2% absolute tolerance, ±2% ratio tolerance) and a ±100ppm/°C temperature coefficient, it ensures reliable performance across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for moderate-power circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal stability and durability.

GS4B012490GGT Features

• Bussed Network: 7 resistors connected in a bus configuration, simplifying PCB layout.
• Thin-Film Technology: Delivers high precision and low noise for sensitive analog/digital circuits.
• Robust Construction: Ceramic package ensures excellent thermal dissipation and mechanical strength.
• Tight Tolerances: ±2% absolute and ratio tolerance for consistent performance.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Automation-Friendly: Gull-wing leads and 1.27mm terminal pitch compatible with standard SMD processes.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4B012490GGT Applications

• Voltage Divider Networks: Precision dividers in sensor interfaces or ADC circuits.
• Bus Termination: Signal integrity in high-speed digital systems (e.g., memory buses).
• Industrial Electronics: PLCs, motor drives, and power supplies requiring stable resistance.
• Automotive (Non-Automotive Rated): Secondary systems where 125°C tolerance is sufficient.
• Test & Measurement Equipment: Calibration circuits due to low TCR and tight tolerances.

Conclusion of GS4B012490GGT

The GS4B012490GGT excels in applications demanding precision, thermal stability, and compactness, leveraging its ceramic SOIC package and thin-film technology. While not PPAP or automotive-qualified, its 2% tolerance, bussed design, and 100V rating make it ideal for industrial, telecom, and instrumentation designs. Its balance of performance and manufacturability positions it as a cost-effective alternative to discrete resistors in space-constrained PCBs.
