GS4A021803FT

GS4A021803FT Description

The GS4A021803FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 180KΩ resistance and a tight ±1% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and delivers a power rating of 0.1W per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures stability under thermal stress, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits. Encased in a rectangular ceramic SOIC package, it offers superior thermal and mechanical robustness compared to standard plastic alternatives.

GS4A021803FT Features

• Isolated Resistors: Four independent 180KΩ resistors with 1% absolute tolerance for precise signal conditioning.
• High Stability: ±50ppm/°C TCR and ceramic substrate minimize resistance drift.
• Robust Construction: Ceramic case enhances thermal dissipation and durability in harsh environments.
• Surface-Mount Design: Gull-wing terminals with 1.27mm pitch for reliable PCB mounting.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-Automotive: Ideal for industrial and commercial applications where PPAP compliance is not required.

GS4A021803FT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring low drift.
• Medical Equipment: Signal isolation in diagnostic devices where accuracy is critical.
• Test & Measurement: Calibration tools and instrumentation needing stable resistance values.
• Industrial Controls: PLCs and motor drives benefiting from ceramic-packaged reliability.
• Telecom Hardware: Impedance matching in RF modules due to low parasitic effects.

Conclusion of GS4A021803FT

The GS4A021803FT stands out for its ceramic-based isolation, tight tolerances, and thermal resilience, making it a superior choice over plastic-encased networks in demanding environments. While not RoHS-compliant, its thin-film technology and gull-wing termination ensure repeatable performance in precision electronics. Engineers will value its balance of compact size, power handling, and stability for critical analog designs.
