GS4B016492JFT Description

The GS4B016492JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Encased in a ceramic substrate, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and a 5% tolerance on its 64.9KΩ resistance value. Rated for 0.05W (1/20) per resistor (0.4W total), it operates across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The gull-wing termination and surface-mount design ensure reliable PCB integration, while its 100V maximum voltage rating supports robust circuit protection.

GS4B016492JFT Features

• Ceramic Construction: Enhances durability and heat dissipation vs. polymer-based networks.
• Bussed Network (BUS): Simplifies circuit design by interconnecting resistors, reducing component count.
• Thin-Film Technology: Delivers tighter ratio tolerance (±1%) and lower noise compared to thick-film alternatives.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for high-density layouts.
• Automotive-Grade Alternatives: While this model is not PPAP/automotive-certified, its 125°C max operating temp suits industrial and telecom applications.
• Non-RoHS Compliant: Ideal for legacy systems or niches exempt from RoHS restrictions.

GS4B016492JFT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Industrial Controls: PLCs and motor drives where temperature stability (±100ppm/°C) is critical.
• Power Management: Current-limiting networks in DC-DC converters or LED drivers.
• Legacy Electronics Repair: Replacing obsolete through-hole networks with space-saving SMD equivalents.

Conclusion of GS4B016492JFT

This resistor network excels in reliability-driven designs requiring stable performance under thermal stress. Its ceramic SOIC package and bussed architecture streamline PCB layouts, while the thin-film technology ensures consistent accuracy. Though not RoHS-compliant, it fills a niche in industrial and high-temperature applications where alternatives fall short. Engineers will value its balance of precision, power handling, and compactness in demanding circuits.
