GUS-QS8B-00-4870-JF Description

The GUS-QS8B-00-4870-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 487Ω resistance value and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for demanding environments. Its ±250ppm/°C temperature coefficient ensures stable performance under thermal stress. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.

GUS-QS8B-00-4870-JF Features

• Circuit Designator: BUS configuration for streamlined signal routing.
• Thin-Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• High Power Handling: 0.05W per resistor (total 0.75W) with 100V maximum voltage rating.
• Robust Construction: QSOP package with ±0.1mm height/length and ±0.2mm depth tolerances for consistent manufacturability.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance is not required.
• Non-RoHS: Suitable for legacy or exempted designs.

GUS-QS8B-00-4870-JF Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Digital Systems: Pull-up/pull-down resistor arrays for buses (e.g., I2C, SPI).
• Power Management: Current-limiting and load-sharing in low-power DC/DC converters.
• Test & Measurement Equipment: High-stability reference networks due to low TCR (±250ppm/°C).
• Industrial Controls: Durable performance in PLCs and sensor interfaces.

Conclusion of GUS-QS8B-00-4870-JF

The GUS-QS8B-00-4870-JF combines high power density, tight tolerances, and thermal resilience in a space-saving QSOP package. Its thin-film technology and BUS-oriented design make it a superior choice for applications requiring repeatable performance without automotive-grade overhead. While not RoHS-compliant, it remains a cost-effective solution for legacy or exempted systems. Engineers will appreciate its balance of precision, reliability, and ease of integration in complex PCB layouts.
