GS4B034302JAT Description

The GS4B034302JAT from TT Electronics/IRC is a high-performance 7-resistor thin-film network in an 8-pin SOIC package, designed for precision applications requiring stable resistance values. With a 43K Ohm resistance per element (±5% tolerance) and a ±25ppm/°C temperature coefficient, it ensures reliable performance across a 70°C to 125°C operating range. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the 0.4W total power rating (0.05W per resistor) supports moderate power dissipation. Its 100V maximum voltage rating and thin-film technology provide excellent stability for signal conditioning, voltage division, and bus termination in demanding environments.

GS4B034302JAT Features

• Precision Network: 7 resistors, each 43K Ohm ±5%, with ±25ppm/°C thermal stability.
• Robust Construction: Ceramic substrate and SOIC-8 package ensure durability and heat dissipation.
• Surface-Mount Ready: Gull-wing leads (1.27mm pitch) for automated PCB assembly.
• Wide Operating Range: Functions from -55°C to +125°C (derated above 70°C).
• Low Power Dissipation: 0.05W per resistor (0.4W total) for energy-sensitive designs.
• High Voltage Tolerance: 100V rating suits industrial and instrumentation circuits.
• Non-Automotive: Ideal for industrial, telecom, and test equipment (PPAP not required).

GS4B034302JAT Applications

This resistor network excels in:

1. Bus Termination: Stable impedance matching for digital communication lines (e.g., CAN, I2C).
2. Signal Conditioning: Precision voltage dividers in sensor interfaces or ADC front-ends.
3. Embedded Systems: Space-efficient resistance arrays for microcontroller peripherals.
4. Test & Measurement: Low-drift performance in calibration circuits or load simulation.
