GS4B022742FFT

GS4B022742FFT Description

The GS4B022742FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 27.4KΩ resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched-resistor circuits. The thin-film technology delivers excellent stability with a low ±50ppm/°C temperature coefficient, making it suitable for precision analog and digital systems. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.

GS4B022742FFT Features

• Ceramic Case (SOIC Package): Enhances thermal performance and durability in harsh environments.
• Bussed Network (7 Resistors): Simplifies circuit design by interconnecting resistors, reducing component count.
• High Precision: ±1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Withstands high temperatures (up to 125°C) and derated power conditions.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation use where automotive compliance isn’t required.

GS4B022742FFT Applications

This resistor network excels in:

• Voltage Divider Circuits: Precision ratio tolerance ensures accurate signal scaling.
• Analog Signal Conditioning: Stable performance in op-amp feedback networks and sensor interfaces.
• Digital Systems: Pull-up/pull-down resistor arrays for buses (e.g., I2C, SPI).
• Power Management: Current-limiting or biasing in low-power DC/DC converters.
• Test & Measurement Equipment: Reliable operation in calibration circuits due to low TCR.

Conclusion of GS4B022742FFT

The GS4B022742FFT combines precision, compactness, and thermal resilience, making it a superior choice for high-reliability electronics. Its bussed design reduces layout complexity, while the ceramic SOIC package offers mechanical and thermal advantages over plastic alternatives. Though not RoHS-compliant, it remains a go-to solution for industrial and telecom designs demanding tight-tolerance, stable resistor networks. Engineers will appreciate its balance of performance, size, and cost in space-constrained, temperature-variable applications.
