GS4B014871FAT

GS4B014871FAT Description

The GS4B014871FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 4.87KΩ value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, this network offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. Its compact dimensions (4.9mm × 5.99mm × 1.45mm) and surface-mount design optimize PCB space efficiency.

GS4B014871FAT Features

• High Precision: Thin-film technology ensures low TCR (±100ppm/°C) and 1% tolerance for reliable signal integrity.
• Robust Construction: Ceramic substrate enhances thermal stability and durability in harsh environments.
• Space-Saving: SOIC-8 package with 1.27mm terminal pitch enables high-density PCB layouts.
• Wide Operating Range: Derated power up to 125°C for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Low Power Dissipation: 0.05W per resistor (0.4W total) balances performance with energy efficiency.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.

GS4B014871FAT Applications

• Analog Signal Conditioning: Precision voltage dividers, gain networks in op-amp circuits.
• Digital Systems: Pull-up/pull-down resistor arrays for buses (e.g., I2C, SPI).
• Industrial Controls: Sensor interfaces, PLCs, and instrumentation requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits, reference networks.
• Power Management: Feedback networks in DC-DC converters or voltage regulators.

Conclusion of GS4B014871FAT

The GS4B014871FAT excels in applications demanding precision, thermal resilience, and compactness. Its thin-film ceramic construction, tight tolerances, and gull-wing SMD compatibility make it a superior choice over thicker-film or less stable alternatives. While not automotive-grade, its wide temperature range and robust design cater to industrial, telecom, and high-reliability electronics. Engineers will value its balance of performance, size, and cost in space-constrained, precision-critical designs.
