GUS-QS0B-03-4752-JB Description

The GUS-QS0B-03-4752-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 47.5K Ohm resistance value and a tight ±5% tolerance. The network operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 1W (0.05W per resistor). Its ±25ppm/°C temperature coefficient ensures stability in thermally dynamic environments, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS0B-03-4752-JB Features

• Thin-Film Technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
• High Power Density: 1W total dissipation in a miniature footprint, ideal for densely populated boards.
• Broad Temperature Range: Operates up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down networks.
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring leaded components.

GUS-QS0B-03-4752-JB Applications
