GUS-QS8A-03-7500-JB Description

The GUS-QS8A-03-7500-JB from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount PCB assemblies. This 750Ω thin-film resistor array features a 5% tolerance, ±25ppm/°C temperature coefficient, and a 0.75W (3/4W) total power rating, with each resistor rated at 0.1W (1/10W). Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers excellent stability and reliability across a wide temperature range of 70°C to 125°C. Its 100V maximum voltage rating and isolated circuit design (ISOL) make it ideal for applications requiring electrical separation between channels. The device is supplied in a tube packaging for automated assembly processes.

GUS-QS8A-03-7500-JB Features

• High Precision: Thin-film technology ensures low noise and tight tolerance (±5%) for stable performance.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) with derating up to 125°C.
• Compact & Durable: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch, suitable for high-density layouts.
• Wide Operating Range: Stable performance from 70°C to 125°C, with a ±25ppm/°C TCR for minimal resistance drift.
• Isolated Design: Independent resistors (ISOL) prevent cross-talk, ideal for multi-channel circuits.
• Automation-Friendly: Gull-wing leads and tube packaging streamline pick-and-place assembly.
