GS4A0234R0DT

GS4A0234R0DT Description

The GS4A0234R0DT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 34Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, this ceramic-based thin-film network ensures stability across a wide temperature range (70°C to 125°C). Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly, while the compact dimensions (4.9mm x 5.99mm x 1.45mm) optimize space efficiency.

GS4A0234R0DT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Stability: Thin-film technology and ceramic substrate ensure minimal drift under thermal stress.
• Precision Performance: ±0.5% absolute tolerance and ±50ppm/°C TCR for critical signal conditioning.
• Robust Construction: SOIC package with gull-wing leads for mechanical durability and solderability.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C for high-reliability environments.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance is not required.

GS4A0234R0DT Applications

• Voltage Dividers & Sensor Interfaces: Precision resistance matching for ADC/DAC reference circuits.
• Medical Equipment: Stable performance in diagnostic devices where thermal drift is critical.
• Test & Measurement: Calibration systems requiring low TCR and tight tolerance.
• Power Supply Feedback Networks: Isolated resistors for feedback loops in DC-DC converters.
• Industrial Control Systems: Signal isolation in PLCs and motor drives.

Conclusion of GS4A0234R0DT

The GS4A0234R0DT excels in applications demanding high precision, thermal stability, and compact form factors. Its isolated design, combined with TT Electronics/IRC’s thin-film expertise, offers superior performance over standard thick-film networks. While not RoHS-compliant, it remains a top choice for non-automotive industrial and telecom systems where reliability and accuracy are paramount. Engineers will appreciate its balance of size, performance, and versatility in critical analog designs.
