GS4A011201DAT

GS4A011201DAT Description

The GS4A011201DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. Housed in an 8-pin narrow SOIC (SOIC-C) package, it features four isolated thin-film resistors, each with a 1.2 kΩ resistance and an absolute tolerance of ±0.5%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient (±100 ppm/°C), ensuring stable performance in varying thermal conditions. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.

GS4A011201DAT Features

• High Precision: ±0.5% absolute tolerance and ±0.05% ratio tolerance for matched resistance values.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Isolated Design: Four independent resistors (ISOL circuit designator) for flexible circuit configurations.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Low TCR: ±100 ppm/°C minimizes resistance drift under temperature fluctuations.
• Surface-Mount Ready: SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances for precise placement.

GS4A011201DAT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to tight tolerance and low TCR.
• Signal Conditioning: Used in sensor interfaces and instrumentation amplifiers.
• Industrial Electronics: Suitable for PLCs, motor controls, and power management systems.
• Medical Devices: Reliable performance in diagnostic equipment where stability is critical.
• Automotive (Non-Automotive Rated): Auxiliary systems requiring robust, temperature-stable components.

Conclusion of GS4A011201DAT

The GS4A011201DAT excels in applications demanding high precision, thermal stability, and compact form factors. Its ceramic construction, isolated resistors, and tight tolerances distinguish it from generic resistor networks, making it a preferred choice for industrial, medical, and instrumentation designs. While not PPAP or automotive-qualified, its performance metrics align with rigorous commercial and industrial standards. Engineers seeking reliable, space-efficient resistor networks will find this model a compelling solution.
