GS4B014992JDT Description

The GS4B014992JDT from TT Electronics/IRC is a high-reliability 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable performance across a wide temperature range. Built with thin-film technology on a ceramic substrate, it delivers excellent thermal stability with a ±100ppm/°C temperature coefficient. The network features a 49.9KΩ resistance per element with a ±5% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent signal integrity in matched circuits. Its SOIC-C series construction offers robust mechanical durability, while the gull-wing termination enables secure surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates reliably from 70°C to 125°C with derated power handling.

GS4B014992JDT Features

• Bussed Network Design: Simplifies PCB layout by integrating 7 resistors with a common node, reducing component count.
• High-Temperature Stability: Ceramic case and thin-film technology ensure minimal drift (±100ppm/°C) in harsh environments.
• Precision Tolerance: ±5% absolute and ±0.5% ratio tolerance for balanced performance in differential circuits.
• Robust Packaging: 8-pin SOIC with gull-wing leads for secure SMT mounting; 1.27mm terminal pitch accommodates high-density designs.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
• Non-Automotive Grade: Ideal for industrial and telecom applications where PPAP compliance is not required.

GS4B014992JDT Applications

• Voltage Divider Networks: Precision-matched resistors for ADC/DAC reference circuits.
• Signal Conditioning: Buffering and termination in data acquisition systems.
• Industrial Controls: Stable performance in PLCs, motor drives, and power supplies.
• Telecom Equipment: Impedance matching and filtering in high-frequency modules.
• Test & Measurement: Calibration circuits requiring tight tolerance ratios.

Conclusion of GS4B014992JDT

The GS4B014992JDT excels in applications demanding high stability, compact integration, and cost-effective resistor networks. Its ceramic thin-film construction, tight tolerances, and bussed topology make it superior to standard thick-film arrays in precision environments. While not RoHS-compliant or automotive-rated, it is a robust choice for industrial, telecom, and instrumentation designs where reliability and thermal performance are critical. Engineers benefit from its reduced BOM complexity and consistent performance across temperature fluctuations.
