GS4A031781FT

GS4A031781FT Description

The GS4A031781FT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolated circuit (ISOL) applications, housed in an 8-pin narrow SOIC ceramic package. This thin-film resistor network offers a 1.78KΩ resistance per element with a tight ±1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The SOIC-C series construction provides 0.1W (1/10W) power dissipation per resistor (0.4W total), with a 100V maximum voltage rating, making it suitable for precision analog and signal conditioning circuits. Its gull-wing termination and surface-mount design facilitate automated PCB assembly, while the ceramic case ensures durability in harsh environments.

GS4A031781FT Features

• High Precision: ±1% absolute tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic SOIC package with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance).
• Isolated Resistors: Independent elements (non-bussed) for flexible circuit design.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Low Noise: Thin-film technology minimizes parasitic effects.
• Automation-Friendly: 1.27mm terminal pitch and gull-wing leads for SMT compatibility.
• Non-Automotive/Non-PPAP: Ideal for industrial, telecom, and instrumentation use.

GS4A031781FT Applications

This resistor network excels in:

• Signal Isolation & Conditioning: Precision dividers, feedback networks in op-amp circuits.
• Medical & Test Equipment: High-stability analog front-end designs.
• Telecom Infrastructure: Impedance matching and filtering in RF modules.
• Industrial Controls: Sensor interfaces, PLCs, and power management systems.
• Aerospace & Defense: Reliable performance in extreme environments (non-RoHS).

Conclusion of GS4A031781FT

The GS4A031781FT stands out for its precision, isolation capability, and ceramic-packaged reliability, making it a superior choice over plastic-encased networks in demanding applications. While not RoHS-compliant, its thin-film stability and rugged SOIC form factor cater to specialized sectors requiring long-term accuracy. Engineers will value its low TCR, high voltage tolerance, and SMT-ready design for critical analog circuits where component consistency is paramount.
