ORNA1003AT0

ORNA1003AT0 Description

The ORNA1003AT0 from Vishay is a high-precision thin-film resistor network designed for applications requiring tight tolerance and stable performance. This 4-resistor isolated network features a 100K Ohm resistance per element with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a molded epoxy SOIC-8 package, it offers 0.4W total power dissipation (0.1W per resistor) and operates reliably within a -55°C to +125°C range, derating up to 150°C. Its gull-wing termination and 1.27mm pitch facilitate easy surface-mount assembly, while the 100V maximum voltage rating enhances versatility in high-impedance circuits. Packaged in tape and reel (T/R), it is optimized for automated PCB assembly.

ORNA1003AT0 Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR for stable, high-accuracy signal conditioning.
