GS4A0226R1FT

GS4A0226R1FT Description

The GS4A0226R1FT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 26.1Ω resistance per element with a tight ±1% tolerance, this thin-film ceramic-based network ensures stable performance across a -70°C to +125°C temperature range, supported by a low ±50ppm/°C temperature coefficient. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic case enhances thermal and mechanical durability.

GS4A0226R1FT Features

• Isolated Resistor Network: Four independent resistors (26.1Ω each) with 1% absolute tolerance for precision signal conditioning.
• Robust Construction: Ceramic SOIC package (4.9mm × 5.99mm × 1.45mm) ensures high thermal stability and vibration resistance.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Low TCR: ±50ppm/°C minimizes resistance drift in fluctuating environments.
• Surface-Mount Optimized: Gull-wing leads and 1.27mm pitch comply with automated assembly processes.
• High Voltage Handling: 100V rating per resistor, ideal for industrial and instrumentation applications.

GS4A0226R1FT Applications

• Precision Voltage Dividers: Used in sensor interfaces and ADC/DAC reference circuits.
• Medical Electronics: Stable performance in patient monitoring equipment.
• Industrial Controls: Signal isolation in PLCs and motor drives.
• Automotive Systems (non-AECQ): Non-safety-critical modules like infotainment.
• Test & Measurement: Calibration circuits requiring low TCR and tight tolerance.

Conclusion of GS4A0226R1FT

The GS4A0226R1FT excels in applications demanding high precision, thermal resilience, and compact form factors. Its ceramic construction, isolated design, and low TCR distinguish it from polymer-based networks, offering superior long-term reliability. While not PPAP or automotive-qualified, it is ideal for industrial, medical, and instrumentation designs where stability and space efficiency are critical. Engineers benefit from its repeatable performance and compatibility with high-volume SMT processes.
