GS4A035112BBT Description

The GS4A035112BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 51.1 kΩ resistance and an exceptional ±0.1% absolute tolerance. Its ±25 ppm/°C temperature coefficient ensures stable performance across a wide operating range (70°C to 125°C). The SOIC-C series construction offers 0.4W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical reliability.

GS4A035112BBT Features

• High Precision: ±0.1% tolerance and ±0.1% ratio tolerance for critical signal conditioning.
• Stable Performance: Low ±25 ppm/°C TCR ensures minimal drift under thermal stress.
• Robust Construction: Ceramic substrate with SOIC package (4.9mm x 5.99mm x 1.45mm) for durability.
• Isolated Resistors: Four independent 51.1 kΩ resistors (non-bussed) for flexible circuit design.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive environments (though not PPAP/automotive-qualified).
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for reliable soldering.

GS4A035112BBT Applications

• Precision Voltage Dividers: Used in ADC/DAC reference circuits and sensor interfaces.
• Medical Equipment: High-accuracy signal processing in diagnostic devices.
• Test & Measurement: Calibration circuits and instrumentation requiring tight tolerance.
• Industrial Controls: Feedback networks in power supplies and motor drives.
