GUS-QS8A-03-1401-JA Description

The GUS-QS8A-03-1401-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.4KΩ resistance value with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a 16-pin QSOP package with gull-wing terminations, it offers a compact 4.9mm x 6.02mm footprint and a low profile (1.47mm height), making it ideal for space-constrained surface-mount (SMD) designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling with precision.

GUS-QS8A-03-1401-JA Features

• Thin-film technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated circuit design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• High power density: 0.1W per resistor (total 0.75W) in a compact QSOP package.
• Wide operating range: Reliable performance from -55°C to +125°C (derated above 70°C).
• Robust construction: Gull-wing terminals and 0.64mm pitch ensure secure PCB mounting.
• Non-automotive grade: Suitable for industrial, telecom, and instrumentation applications.
