GS4A011802FT

GS4A011802FT Description

The GS4A011802FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each rated at 18KΩ with a tight ±1% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a robust rectangular ceramic SOIC package, it offers excellent thermal stability across an operating range of 70°C to 125°C, with a derated power handling capability. The 0.1W (1/10W) power rating per resistor and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination ensures reliable surface-mount assembly, while the 4.9mm × 5.99mm compact footprint optimizes PCB space utilization.

GS4A011802FT Features

• Isolated Circuit Design (ISOL): Ensures minimal crosstalk between resistors, ideal for precision signal conditioning.
• High-Temperature Stability: Operates reliably up to 125°C with a derated power profile.
• Thin-Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• 1% Absolute Tolerance: Guarantees consistent performance in critical analog/digital circuits.
• Ceramic Case: Enhances durability and heat dissipation in harsh environments.
• RoHS Non-Compliant: Suitable for legacy or specialized industrial applications where RoHS restrictions do not apply.

GS4A011802FT Applications

This resistor network excels in:

• Isolation Circuits: Signal isolation in medical devices or industrial sensors.
• Voltage Dividers: Precision dividers in ADC/DAC reference circuits.
• Termination Networks: High-speed data line termination (e.g., LVDS, USB).
• Automotive/Industrial Electronics: Despite its non-automotive PPAP status, it suits non-safety-critical subsystems like HVAC controls or power management.
• Test & Measurement Equipment: Stable resistance for calibration and feedback loops.

Conclusion of GS4A011802FT

The GS4A011802FT stands out for its ceramic-based isolation, thin-film precision, and compact SOIC form factor, making it a robust choice for engineers prioritizing thermal stability and signal integrity. While not RoHS-compliant or PPAP-qualified, its 18KΩ isolated resistors with ±1% tolerance fill a niche in industrial, medical, and instrumentation designs where reliability trumps regulatory constraints. For applications demanding low TCR and high voltage handling in constrained spaces, this network offers a compelling balance of performance and durability.
